- FIG. 1 of the drawings provides a schematic representation of grape production across the United States with black dots representing the areas or regions of production and the size of the dots indicating the relative quantities of production. As shown in FIG. 1, California is the largest grape producer followed by New York, Washington, Michigan, Pennsylvania, Ohio, Arizona, and Arkansas.
- the American-type, V. labruscana , or its hybrids with viniferas are grown mainly in the central and northeastern states.
- Muscadine, Vitis rotundifolia is grown mainly in the gulf and southern Atlantic states.
- ‘Thompson Seedless’ The largest acreage of ‘Thompson Seedless’ is explained by the fact that this cultivar is popular for raisins, table grapes, wine, juice, and canning and therefore constitutes the majority of California's grape acreage (R-raisin; T-table; W-wine; w-white; r-red).
- trellis systems should be devised and shoots positioned to accommodate precise mechanical movement. These operations should occur without excessive damage to the vines and at no reduction in fruit yield and/or quality.
- GDC Geneva Double Curtain training system
- the GDC trellising system (FIG. 75) doubles the length of cordon per vine, over the 5 ⁇ fraction (1/2) ⁇ to 6 ft. (165 cm-170 cm) Single Curtain, Bilateral Cordon (BC) which is also easy to totally mechanize when the fruiting canes are selected from the lower 180° of the cordon for cultivars with drooping growth habit.
- BC Bilateral Cordon
- the GDC trellising system requires a 3-wire trellis with two horizontal cordon-support wires and a single trunk-support wire.
- the cordon support wires should be 180 cm above the ground and 120 cm apart.
- the vines are cordon trained and short cane pruned (i.e., 4 to 6 nodes) for most Vitis labruscana species.
- the cordon wires are attached to flexible cross arms that allow for efficient and total mechanization (FIG. 75).
- Vitis vinifera L. the fruiting canes of Vitis labruscana , cordon-trained vines are selected from nodes of very short vertical arms originating within the lower 180° of the horizontal cordon.
- the cordon must be in continuous contact with the support wire in order to obtain maximum efficiency from mechanical operations.
- BC Bilateral cordon trained Vitis labruscana vines
- FIGS. 2 and 3 also can be effectively shoot positioned, pruned, thinned, and harvested by machine (2, 23, 24, 25).
- Research in Arkansas (2, 24) compared the three major trellising systems used for Vitis labruscana grapes in the Eastern United States, and the results have shown the BC system to be as productive and to produce comparable fruit quality to the Umbrella Kniffin system, the predominate trellising system that was used at the time of the study.
- the GDC system proved to be even more productive than either of the other two systems, with no reduction in fruit quality.
- the GDC system has proven to be superior to the BC system with vigorous cultivars that have sufficient growth to fill the trellis of the GDC system. However, there is no advantage to the GDC system in low vigor vineyards without the utilization of close in-row spacing.
- the BC and GDC system can be completely mechanized; hence, these systems as well as the modified systems of FIGS. 76 - 82 and the like are the recommended or preferred systems for most cultivars and vineyards that are to be partially or totally mechanized.
- Bilateral cordon (BC) with a (105 cm) 42-inch cordon and two stationary top catch wires on a vertical trellis or moveable catch wires utilizing spur pruning on the upper 180° of the cordon currently are common training systems in Vitis vinifera vineyards in many parts of the world (FIG. 30).
- the fruiting spurs are selected from the upper 180° of the cordon since Vitis vinifera cultivars grow upright.
- a 210 cm stake is driven into the ground to a depth of 50 cm at each vine.
- One or two 12-gauge high tensile strength (HTS) cordon wires are located about 105 cm above the vineyard floor.
- moveable catch wire system two or three moveable foliage support wires (13-gauge HTS) are moved upward to support the new growth as the vine grows.
- moveable catch wire system two or three moveable foliage support wires (13-gauge HTS) are moved upward to support the new growth as the vine grows.
- These systems can be successfully pruned, thinned, fruiting zone leaf removed, summer tipped or trimmed, and harvested mechanically.
- a mechanical pruning aid for Concord grapes was developed in New York by Pollock et al. (32) for use on cordon-trained vines.
- a triangular arrangement of reciprocating cutter bars established the length of cane and cane position.
- This New York pruning system was supplemented by a mechanized brushing technique to remove the top shoots (upper 180° of the cordon) early in the spring.
- the mechanical thinner (shown in FIGS. 53 and 54) in this application has eliminated this concern for BC-trained vines by being able to effectively adjust fruit loads by controlling the beater speed (rpm) of this unit.
- the unit shown in FIGS. 2 - 9 is extremely effective in adjusting crop load with the French-American hybrid and Vitis vinifera grapes.
- This economical thinning system for the BC 170 cm (6 ft.) system is a mechanical thinning unit using bow-rods, fingers, or strikers in an over-the-row beater side-mounted unit built where the operator can see to adjust fruit load on individual vines (FIG. 2 and FIGS. 53 and 54).
- Results are shown in Tables 2 and 3 where less efficient equipment than that discussed in this application was used to accomplish the desired pruning results of mechanical pruning on yield, vine size, and juice quality (Tables 2 and 3) on shoot positioned Concord grapevines on GDC or BC training systems (23,24).
- This study was established in a 20-year old vineyard. The vines were either mechanically pruned or balance pruned to a 30+10 severity. The mechanically pruned vines were left untouched or were adjusted to the best 60 or 90 nodes per vine. After six consecutive years, follow-up pruning by hand, to limit the number of nodes per vine to 60 following mechanical pruning, maintained vine size and produced fruit yield and juice quality comparable to vines balance pruned to a 30+10 schedule in this older vineyard and under conditions of this study.
- Seven pruning treatments a) balance pruned by hand to a 30+10 level (6 node canes), b) balance-pruned by hand to a 50+10 level (6 node canes), c) mechanically pruned and adjusted to the best 60 nodes, d) mechanically pruned and adjusted to the best 80 nodes, e) mechanically pruned with fruit removed by mechanical beating at a green-pea size to a level approximating the fruit load of a 30+10 pruning severity, f) mechanically pruned with no touch-up in even-numbered years and hand pruned to 30+10 (6 node canes) in odd-numbered years, and g) mechanically pruned with no touch-up.
- Pool et al. (35) have used minimal pruning in New York vineyards. Pool (34) has also studied mechanical thinning and found that the resultant crop reduction enhanced juice soluble solids contents.
- the French hybrids are interspecific hybrids that vary a great deal in their vine characteristics, but, in general, the majority of the cultivars that have been selected for production have shorter internodes than the Vitis labruscana species. Most all hybrids tend to be extremely fruitful. This fruitfulness is due to a large extent to the high cluster numbers for shoot and extremely fruitful basal buds. These basal buds are seldom, if ever, fruitful with Vitis labruscana and Vitis vinifera species. These basal buds or nodes are considered non-count on V. labruscana , but on some French hybrids the basal or non-count buds can account for 30-40% of the fruit that is produced.
- Hand thinning is a method to produce consistently high quality fruit from these cultivars. Hand thinning is expensive and one of the greatest challenges in producing these cultivars. To fruit and shoot thin these cultivars mechanically and economically, the mechanical shoot and fruit thinner described in this application (FIGS. 2 - 33 ) is recommended. The fruit zone area for most French hybrids is the same as for the Vitis vinifera species (FIGS. 2 - 7 ). Mechanical crop control of this group of grapes may be accomplished by both mechanical shoot and fruit thinning (FIGS. 2 - 33 ). This new mechanical fruit and shoot thinner is relatively simple and extremely effective.
- Vitis vinifera cultivars have upright growth habits and require that the fruiting zone be located on the upper 180° of the cordon.
- the majority of the premium wine produced in the world comes from this species of grapes.
- Wineries pay premium prices for high quality vinifera grapes.
- the need to restrict crop sizes following mechanical pruning is paramount. These concerns become even greater in regions of the world where there are short growing seasons and potential for winter injury.
- Producers have to go to extreme hand thinning measures to reduce crop loads, to ensure maturity and maximize winter hardiness. In both cases, the need for cluster and/or berry thinning is necessary to adjust the fruit load to the capacity of the vine.
- foliage to fruit ratio for many cultivars has been 10 to 15 square centimeters of leaf to one gram of fruit.
- Dr. Robert Pool a method to estimate crop level to determine the amount of fruit that should be mechanically removed. Assuming the grower knows the number of vines per acre, an estimate of crop weight (lb.) can be calculated. The grower should harvest all fruit from a representative sample (e.g. two post-lengths) at 1200 growing degree-days, or when berries reach 50% of final weight. For ‘Concord’ in NY, Pool has shown that regardless of pruning system, weather, year, or crop level, 50% of final cluster weight will occur at 1200 growing degree days. However, this timing will change for different cultivars and for different grape growing regions.
- the grower then multiplies the weight of fruit per vine at 1200 degree-days by 2 to determine crop weight per vine at harvest. Then multiply lb./vine by vines per acre and divide by 2000 to arrive at tons/acre. If the estimated crop is above the desired tons/acre for maximum quality for the cultivar or vineyard, the grower can calculate the percent of fruit he needs to remove from each vine to arrive at the desired cropping level. As a rule, machine thinning should be used about 20-30 days following bloom in cool growing regions such as the “grape belt” region of New York.

See, for example, FIG. 36 of the drawings which shows respective hydraulic motors for driving each of two rotary units.
- the amount of shoot and fruit thinning that is accomplished using the rotary striker units 20 and 22 and in particular by the striker fingers 24 and 26 of the rotary units 20 and 22 is determined by the speed and direction of the rotary units, the number of striker fingers, the flexibility of the fingers, the spacing of the rotary units and fingers from one another, the alignment of the flexible fingers on the respective rotary units (in sync with one another or out of sync with one another), the speed with which the shoot and fruit thinner 10 is moved through the vineyard and along the vine, and combinations thereof.
- the striker fingers 24 and 26 are attached to or mounted in respective finger receiving sockets 102 and 104 which are attached to respective rings or annuluses 106 and 108 by respective radial support members 110 and 112 (see FIGS. 13 and 14).

- the flexible ends 114 of the adjacent fingers 24 of the finger pair tend to grab foliage, shoots, grape bunches, and the like, during travel of the fingers through the vine. Also, the flexible ends 114 on the fingers allow the ends to bend or give, should they contact a solid item such as a wire, post, brace, stay, trellis member, cordon wire support, cordon, other striker fingers, brushes, brush bristles, or the like.
- a solid item such as a wire, post, brace, stay, trellis member, cordon wire support, cordon, other striker fingers, brushes, brush bristles, or the like.
- the pair of fingers may be further supported by attaching them one to the other near their base by, for example, wrapping tape around the base supports 116 of adjacent fingers. This increases the rigidity of the finger pair and increases the amount of foliage or fruit which is removed during use thereof.

Abstract
For more than thirty-two years, extensive research studies involving various concepts of total vineyard mechanization have been carried out at the Arkansas Agricultural Experiment Station under the direction of Justin R. Morris (22). Tommy Oldridge was one of the first growers in the region to commercially test, implement and improve upon the findings of these research studies. These studies at the University of Arkansas have involved the evaluation of trellising and training systems suitable for total vineyard mechanization, mechanical shoot positioning, mechanical pruning, mechanical thinning, mechanical harvesting, and the post-harvest handling and utilization of mechanically harvested grapes (2, 22, 23, 24, 25, 26, 27, 35). The success of this approach to vineyard mechanization has been the fact that it has concentrated on minimizing or eliminating all limiting factors impacting the system while maintaining, or in some cases improving, fruit quality. Also, the researchers have constantly developed, modified and evaluated new equipment for the mechanization of each viticultural operation requiring hand labor. A major effort has been placed on accomplishing these objectives without any loss in fruit quality.
Description
- This application is a continuation of U.S. patent application Ser. No. 08/950,301 filed Oct. 14, 1997, which is a continuation-in-part of provisional application Serial No. 60/035,216 filed Jan. 7, 1997, and is also a continuation-in-part of provisional application Serial No. 60/049,285 filed Jun. 10, 1997. Each of these provisional applications are hereby incorporated by reference.
- Not Applicable.
- Not applicable.
- The present invention is directed to vineyard apparatus, systems, and methods, and, more particularly concerns, machinery, devices, systems, and methods for completely or partially mechanizing grape growing and harvesting while maintaining or improving vineyard consistency and fruit quality. The present invention applies to both wine and juice grape types, is adapted to a substantial number of different trellis types and training systems, and is especially useful in established vineyards, for example having been trained for about three or more years.
- Grapes are consumed in a larger quantity and in more different product types than any other fruit crop on a global basis. The major uses for grapes are for wine, raisins, fresh market, juice (and concentrate), and in canned products (such as fruit cocktail). Table 1 shows the important grape producing countries of the world.
- Chapter XX, “Grape Growing”, by Justin R. Morris, in the text “Modern Fruit Science” by Norman F. Childers, Justin R. Morris, and G. Steven Sibbet, published by Horticultural Publications, Gainsville, Fla., 1995, is hereby incorporated by reference. More particularly, as described on pages 478-482 including Table III and FIGS.24-27, mechanical pruning equipment has reduced the man hours required for grape pruning. Page 484 describes mechanical harvesting, and page 485 describes the economics of vineyard mechanization. As described on pages 491-494 and as shown in FIGS. 38 and 40, vinifera grapes for processing are mechanically harvested and power pruned using tractor powered, hand-held pneumatic power shears in an effort to reduce labor costs.
- Although mechanical harvesters, mechanical shoot positioners, and mechanical pruning devices have been known for some time, heretofore, a commercially viable and effective system and apparatus for complete mechanization of the growing and harvesting of wine and juice grape cultivars has not been developed. Although attempts have been made at vineyard mechanization, they have fallen short in that they either require excessive follow-up hand operations or other manual labor, do not provide for mechanization of both upright and drooping growth habit grape cultivars, are not adjustable, adaptable, or versatile enough to be used with a multitude of trellis types or training systems, are not cost effective, do not maintain fruit quality, and the like.
- For example, U.S. Pat. Nos. 3,426,517; 3,439,482; 3,473,311; 3,563,016; 3,559,386; 3,601,964; 3,613,343; 3,715,876; 3,727,388; 3,760,574; 3,766,724; 3,783,595; 3,866,401; 3,889,454; 3,890,774; 3,890,775; 3,939,629; 3,996,730; 4,016,711; 4,022,001; 4,035,572; 4,112,657; 4,207,727 4,112,657; 4,207,727; 4,241,569; 4,251,983; 4,282,705; 4,291,526; 4,299,081; 4,321,786; 4,370,847; 4,391,085; 5,339,612; 5,355,667; and 5,423,166 are directed to or disclose grape harvesting or grape harvester equipment or machinery.
- U.S. Pat. No. 5,101,618, issued to Tommy L. Oldridge on Apr. 7, 1992, discloses an improved grapevine comber (shoot positioning) machine or device including a pivoting counterforce brush for use with an underslung grapevine comber for cleaning and positioning shoots of the grapevine overhanging the guide wires of a divided canopy, and is hereby incorporated by reference.
- U.S. Pat. No. 5,544,444, issued to Tommy L. Oldridge on Aug. 13, 1996, discloses a single curtain wine and juice grape vine cane pruner and is hereby incorporated by reference.
- Other patents of general interest include U.S. Pat. No. 3,901,006 directed to a vine combing (shoot positioning) machine, U.S. Pat. No. 4,333,266 directed to a viticultural process and vine-dressing machine, and U.S. Pat. No. 4,638,705 directed to a machine for trimming and disbudding vine shoots for subsequent use as graft supports.
- Hence, there exists a need throughout the viticultural world for an improved vineyard apparatus, system and method for partial or complete vineyard mechanization and to modify, trellis, and train grapevines so that expensive hand operations can be economically mechanized without any substantial loss of yield while maintaining or improving vineyard consistency and fruit quality.
- In accordance with the present invention, a vineyard apparatus, method and system for complete or partial mechanization of grape growing and harvesting or viticulture is provided which addresses the shortcomings of the prior art and makes provision for viticulture mechanization without a substantial decrease in yield and while maintaining or improving vineyard consistency and fruit quality, especially in established vineyards.

The success of this approach to vineyard mechanization has been the fact that it has concentrated on minimizing or eliminating all limiting factors impacting the system while maintaining, or in some cases improving, fruit quality.

- Brief History of Vineyard Mechanization and Concerns
- FIG. 1 of the drawings provides a schematic representation of grape production across the United States with black dots representing the areas or regions of production and the size of the dots indicating the relative quantities of production. As shown in FIG. 1, California is the largest grape producer followed by New York, Washington, Michigan, Pennsylvania, Ohio, Arizona, and Arkansas.
- California produces almost entirely the European-type grapeVitis vinifera. The American-type, V. labruscana, or its hybrids with viniferas are grown mainly in the central and northeastern states. Muscadine, Vitis rotundifolia is grown mainly in the gulf and southern Atlantic states.
- The following are the leading cultivars in California in approximate order by acreage: ‘Thompson Seedless’ (RT); ‘French Colombard’ (wW); ‘Chardonnay’ (wW); ‘Zinfandel’ (rW); ‘Cabernet Sauvignon’ (rW); ‘Flame Seedless’ (T); ‘Flame Tokay’ (T); ‘Merlot’ (rW); ‘Sauvignon blanc’ (wW); ‘Emperor’ (T); ‘Grenache’ (rW); ‘Carignane’ (rW); ‘Barbera’ (rW); ‘Perlette’ (T); ‘Pinot Noir’ (rW); ‘Ruby Cabernet’ (rW); ‘White Riesling’ (wW); ‘Muscat of Alexandria’ (wW); ‘Petite Sirah’ (rW); ‘Rubired’ (rW); ‘Chenin blanc’ (wW); ‘Pinot blanc’ (wW); ‘Semillon’ (wW); ‘Ribier’ (T); ‘Gewurztraminer’ (wW); ‘Napa Gamay’ (rW); ‘Nebbiolo’ (rW); and ‘Malvasia Bianca’ (wW). The largest acreage of ‘Thompson Seedless’ is explained by the fact that this cultivar is popular for raisins, table grapes, wine, juice, and canning and therefore constitutes the majority of California's grape acreage (R-raisin; T-table; W-wine; w-white; r-red).
- To use machines successfully for mechanical shoot positioning, mechanical pruning, mechanical thinning, mechanical shoot removal, mechanical leaf removal, mechanical harvesting, and other grape production operations, trellis systems should be devised and shoots positioned to accommodate precise mechanical movement. These operations should occur without excessive damage to the vines and at no reduction in fruit yield and/or quality.
- One training system that addresses these objectives is the Geneva Double Curtain training system (GDC), developed by Shaulis et al. (38) in New York. The GDC trellising system (FIG. 75) doubles the length of cordon per vine, over the5{fraction (1/2)} to 6 ft. (165 cm-170 cm) Single Curtain, Bilateral Cordon (BC) which is also easy to totally mechanize when the fruiting canes are selected from the lower 180° of the cordon for cultivars with drooping growth habit. The proper use of a mechanical shoot positioner increases the number of mature, productive shoots on vigorous vines that have their basal nodes adequately exposed to sunlight. Most vigorous vines of large-leafed Vitis labruscana L., Vitis aestivalis, some American hybrids, French-American hybrids and a few Vitis vinifera cultivars with a drooping-shoot growth habit and annual cane prunings of 1.35 kg or more at spacings of 240 cm in-the-row spacing may be expected to give excellent response to the GDC system (17). Less vigorous vines need to be spaced closer in the row or be grown on the BC high wire system.
- The GDC trellising system requires a 3-wire trellis with two horizontal cordon-support wires and a single trunk-support wire. The cordon support wires should be 180 cm above the ground and 120 cm apart. The vines are cordon trained and short cane pruned (i.e., 4 to 6 nodes) for mostVitis labruscana species. The cordon wires are attached to flexible cross arms that allow for efficient and total mechanization (FIG. 75). In contrast to Vitis vinifera L., the fruiting canes of Vitis labruscana, cordon-trained vines are selected from nodes of very short vertical arms originating within the lower 180° of the horizontal cordon. The cordon must be in continuous contact with the support wire in order to obtain maximum efficiency from mechanical operations.
- Bilateral cordon (BC) trainedVitis labruscana vines (FIGS. 2 and 3) also can be effectively shoot positioned, pruned, thinned, and harvested by machine (2, 23, 24, 25). Research in Arkansas (2, 24) compared the three major trellising systems used for Vitis labruscana grapes in the Eastern United States, and the results have shown the BC system to be as productive and to produce comparable fruit quality to the Umbrella Kniffin system, the predominate trellising system that was used at the time of the study. However, the GDC system proved to be even more productive than either of the other two systems, with no reduction in fruit quality. The GDC system has proven to be superior to the BC system with vigorous cultivars that have sufficient growth to fill the trellis of the GDC system. However, there is no advantage to the GDC system in low vigor vineyards without the utilization of close in-row spacing. The BC and GDC system can be completely mechanized; hence, these systems as well as the modified systems of FIGS. 76-82 and the like are the recommended or preferred systems for most cultivars and vineyards that are to be partially or totally mechanized.
- Bilateral cordon (BC) with a (105 cm) 42-inch cordon and two stationary top catch wires on a vertical trellis or moveable catch wires utilizing spur pruning on the upper 180° of the cordon currently are common training systems inVitis vinifera vineyards in many parts of the world (FIG. 30). The fruiting spurs are selected from the upper 180° of the cordon since Vitis vinifera cultivars grow upright. A 210 cm stake is driven into the ground to a depth of 50 cm at each vine. One or two 12-gauge high tensile strength (HTS) cordon wires are located about 105 cm above the vineyard floor. However, with the moveable catch wire system two or three moveable foliage support wires (13-gauge HTS) are moved upward to support the new growth as the vine grows. These systems can be successfully pruned, thinned, fruiting zone leaf removed, summer tipped or trimmed, and harvested mechanically.
- Mechanical Shoot Positioning:
- Effective mechanical pruning only can be accomplished with species with a drooping growth habit when produced on a 170 cm (6 ft.) GDC or BC system when the vines are shoot positioned, which places the canes in proper position for the winter mechanical pruning operation. See Oldridge Patent No. 5,101,618, dated Apr. 7, 1992 and hereby incorporated by reference, for a GDC vine comber with pivoting counterforce brush. Also, see FIGS.41-43 for positioning and pruning equipment. Shoot positioning has been shown to be an effective method of improving fruit quality and of exposing the lower nodes on the bearing units (canes) to sunlight to make the basal nodes more productive than under shaded conditions (27, 38, 40). Shoot positioning has proven particularly effective with large vigorous vines on GDC which have a drooping-shoot growth habit. Shoot positioning can be accomplished by mechanical means. A new shoot positioner patented and manufactured by Tommy Oldridge is an improvement over other machines for the positioning of GDC-trained vines (FIG. 42 and U.S. Pat. No. 5,101,618 to Oldridge).
- As soon as the tendrils touch the wire or another cane, they fasten very quickly; therefore, vines are usually first shoot positioned just before bloom. Shoot positioning may require a second pass with a mechanical shoot positioner. For the GDC system, all vigorous shoots growing between the two cordon wires must be pulled or brushed down in order to maintain two separate foliage canopies. This can be accomplished with the Oldridge shoot positioner and middle breaker (FIGS. 48 and 49). Also, other vineyard operations can be carried out at the same time while the shoots are positioned or broken (spraying, etc.).
- Mechanical Pruning and/or Trimming During the Dormant Season:
- In the late 1960s, grape producers indicated that once mechanical harvesting was totally implemented, the most time-consuming hand labor operations in the vineyard were dormant pruning and tying. Grape producers complained of decreasing availability of qualified labor for pruning and tying and indicated that these should be the next operations mechanized (22).
- Background Information on:
- A mechanical pruner or trimmer was successfully tested in 1967 and 1968 by Morris at the University of Arkansas Agricultural Experiment Station on a BC cordon-trained mature Concord vineyard (FIGS.2-7). The most significant findings of these studies were that the vines had to be shoot positioned before and following bloom in order for the canes to be in the proper position for dormant pruning or trimming and equally important was the need to produce the lower nodes in sunlight to maintain node productivity and fruit quality.
- A mechanical pruning aid for Concord grapes was developed in New York by Pollock et al. (32) for use on cordon-trained vines. A triangular arrangement of reciprocating cutter bars established the length of cane and cane position. This New York pruning system was supplemented by a mechanized brushing technique to remove the top shoots (upper 180° of the cordon) early in the spring.
- In1971, the Arkansas studies indicated mechanical pruning of grape vines could be accomplished and would reduce pruning labor by as much as 50% (26). One viticultural concern was observed in this early research, the impossibility of treating each vine individually to control crop load (balance pruning according to vine size), which might result in the overcropping or undercropping of individual vines.
- The mechanical thinner (shown in FIGS. 53 and 54) in this application has eliminated this concern for BC-trained vines by being able to effectively adjust fruit loads by controlling the beater speed (rpm) of this unit. The unit shown in FIGS.2-9 is extremely effective in adjusting crop load with the French-American hybrid and Vitis vinifera grapes. This economical thinning system for the
BC 170 cm (6 ft.) system is a mechanical thinning unit using bow-rods, fingers, or strikers in an over-the-row beater side-mounted unit built where the operator can see to adjust fruit load on individual vines (FIG. 2 and FIGS. 53 and 54). Results are shown in Tables 2 and 3 where less efficient equipment than that discussed in this application was used to accomplish the desired pruning results of mechanical pruning on yield, vine size, and juice quality (Tables 2 and 3) on shoot positioned Concord grapevines on GDC or BC training systems (23,24). This study was established in a 20-year old vineyard. The vines were either mechanically pruned or balance pruned to a 30+10 severity. The mechanically pruned vines were left untouched or were adjusted to the best 60 or 90 nodes per vine. After six consecutive years, follow-up pruning by hand, to limit the number of nodes per vine to 60 following mechanical pruning, maintained vine size and produced fruit yield and juice quality comparable to vines balance pruned to a 30+10 schedule in this older vineyard and under conditions of this study. Both the no-touch-up treatment and retaining 90 nodes per vine following mechanical pruning treatments reduced per vine and per node fruit yields (data not shown) after the sixth year and resulted in unacceptable objective and sensory juice quality. Also, these two treatments resulted in uneven ripening of Concord grapes (% green fruit), which contributed to the problem of low soluble solids and poor juice color. - Sensory color acceptability ratings (Table 3), which included both the parameters of color intensity and hue, generally declined with increasing treatment severity on single curtain SC trained vines. However, the color acceptability was rated lower than expected on hand pruned (30+10) GDC-trained vines because of the blue appearance, rather than the expected intense purple juice color. This result was due to the influence of high pH on juice color. The high pH allowed structural transformations of the anthocyanin molecule, resulting in the shift in hue. SC-trained, no touch-up vines had the lowest ratings for both color intensity and color acceptability.
- Juice flavor was rated unacceptable from plots limited to 90 nodes or with no touch-up on the GDC training system and with no touch-up treatment on the SC system, following mechanical pruning.
- From this study it was concluded that continuous mechanical pruning in Concord vineyards is recommended only in shoot-positioned vineyards where pruning can be followed by cane selection and adequate node limitations. However, recent unpublished data shows that mechanical fruit thinning also eliminates this problem without the need for hand thinning.
- These preliminary findings indicated a need for a better mechanical shoot positioner and mechanical pruner. This unit has been patented by Oldridge, U.S. Pat. No. 5,544,444 hereby incorporated by reference (FIGS.44-47). A study was designed at the Arkansas Agricultural Experiment Station with the objective of examining various levels of mechanical pruning in combination with shoot positioning on Concord grapes. The vineyard was planted in 1981. The vines were extremely uniform in vigor, and all vines were trained to the GDC training system with 3 m×2 m spacing and drip irrigation. The experimental field plot was an incomplete latin square 7×4 factorial (7 columns, 4 rows) with four replications. Treatments consisted of: 1. Four levels of shoot positioning; a) hand positioning, b) machine positioning, c) separating the canopy by breaking centers only, and d) no shoot positioning. (In treatments a, b, and c, the shoots were positioned vertically toward the vineyard floor two or three times, as required). 2. Seven pruning treatments; a) balance pruned by hand to a 30+10 level (6 node canes), b) balance-pruned by hand to a 50+10 level (6 node canes), c) mechanically pruned and adjusted to the best 60 nodes, d) mechanically pruned and adjusted to the best 80 nodes, e) mechanically pruned with fruit removed by mechanical beating at a green-pea size to a level approximating the fruit load of a 30+10 pruning severity, f) mechanically pruned with no touch-up in even-numbered years and hand pruned to 30+10 (6 node canes) in odd-numbered years, and g) mechanically pruned with no touch-up.
- Yield, pruning weight, and juice quality have been determined for eight consecutive years. Unlike some of the recent research findings in other regions, our results indicate that continued mechanical pruning with no node adjustments may have undesirable effects on fruit quality when the mechanical pruning results in extremely high yields (Tables 4 and 5). Our main concern about mechanical pruning is its affect on percent soluble solids and color (Tables 3 and 4). Shoot positioning showed reduction in soluble solids in 1991, but there was no need to position the vines in 1991 due to reduced vigor and vine size (Table 5). It was obvious that shoot positioning for sunlight exposure was not needed. The excessive heat, hot nights, and fruit exposure to the sun was detrimental to the production of soluble solids. This points out the need to maintain vine vigor or size on high yielding vineyards and also again point out the need for selective mechanical fruit thinning in order to maintain balanced high yielding production of high quality fruit.
- Freeman and Cullis (12) studied mechanical hedge pruning of Cabernet Sauvignon and Doradillo vines in Australia that were trained to a BC system. The following hedge shapes were established in this study: 1) a square hedge with three cutting planes that produced a square cross-section (the distance from the cutting plane to the cordon was set to give node numbers that were similar to the controls); 2) an offset rectangular hedge where the vines were trimmed close to the cordon on one side on alternate years to allow for new spurs to develop; and 3) a hedge pruned to a triangular shape on the upper 180° portion of the cordon. The yield and capacity of hedged vines were equal to or greater than the manually-pruned vines, except in 1976, when the hedged Doradillo vines had lower yields. With the Cabernet Sauvignon, a triangular hedge initially had lower yields but in later years yielded more than the square and offset hedges. This increase in Cabernet yield with the triangular hedge was a result of increased berry number compared to the other hedge shapes.
- Freeman and Cullis (12) concluded that under Australian conditions vine hedging was a viable alternative to detailed manual pruning for vinifera grapes in Australia. The major quality characteristics affected by total mechanical pruning are smaller berries and clusters. Minimal pruning ofVitis vinifera vines on a commercial scale is being adopted in Australia. Also, they indicated that the mechanically pruned hedge presents no problems during the mechanical harvesting operation. Machine-assisted pruning has become a fixture in the Australian wine industry (6).
- Minimal Pruning:
- Working on the theory that winter pruning disturbs the vines' natural process of self-regulation of growth and production, Clingeleffer and Possingham (5) have developed a trellising system in Australia that requires minimal pruning and provides ideal vine conformation for mechanical harvesting. They call it Minimal Pruning of Cordon-Trained Vines. Cordon-trained vines are trained to either a single or double high wire in the vertical plane. Pruning consists of trimming at the sides only in the summer and trimming at 30 inches above the ground as a harvest aid. Over the seasons, the cordons and canes grow into a large permanent canopy. Trimming can be accomplished with simple and inexpensive tractor-mounted equipment. Commercial production has been accomplished in Australia and to a limited extent in California with this system.
- Pool et al. (35) have used minimal pruning in New York vineyards. Pool (34) has also studied mechanical thinning and found that the resultant crop reduction enhanced juice soluble solids contents.
- Intrieri and Marangoni (15) reported alternate “up-down” mechanical pruning of GDC-trainedVitis vinifera grapes in Bologna, Italy, has given satisfactory results in terms of production and vegetative response of the vines for a three-year period. After four years of tests and surveys, Cargnello and Lisa (1) in Veneto, Italy, concluded that for mechanical pruning to be practical it is necessary to control the bud load annually, and that mechanical pruning must ensure an adequate number of renewal canes with short cuts on some parts of the cordon to avoid the premature aging of the vine. In some regions, success is not or will not be possible until trellis systems are modified for mechanization. Also, this system will not work in regions with short growing seasons, where harvest may be delayed from big crops, and vines are subject to severe injury from low winter temperatures.
- Parallel work on pruning and shoot positioning mechanization has occurred in other grape growing regions of the world, e.g., New Zealand (42), France (37, 44), Italy (7, 8, 9, 10, 16, 33, 41, 43), Spain (13), Bulgaria (21, 29, 30), and the Ukraine (28).
- Mechanized Systems for the Production of French-American hybrids:
- The French hybrids are interspecific hybrids that vary a great deal in their vine characteristics, but, in general, the majority of the cultivars that have been selected for production have shorter internodes than theVitis labruscana species. Most all hybrids tend to be extremely fruitful. This fruitfulness is due to a large extent to the high cluster numbers for shoot and extremely fruitful basal buds. These basal buds are seldom, if ever, fruitful with Vitis labruscana and Vitis vinifera species. These basal buds or nodes are considered non-count on V. labruscana, but on some French hybrids the basal or non-count buds can account for 30-40% of the fruit that is produced.
- An individual bud of the French-Hybrid is more productive since the secondary bud at each node can produce almost as many grapes as the primary buds.
- Hand thinning is a method to produce consistently high quality fruit from these cultivars. Hand thinning is expensive and one of the greatest challenges in producing these cultivars. To fruit and shoot thin these cultivars mechanically and economically, the mechanical shoot and fruit thinner described in this application (FIGS.2-33) is recommended. The fruit zone area for most French hybrids is the same as for the Vitis vinifera species (FIGS. 2-7). Mechanical crop control of this group of grapes may be accomplished by both mechanical shoot and fruit thinning (FIGS. 2-33). This new mechanical fruit and shoot thinner is relatively simple and extremely effective.
- Mechanization of theVitis vinifera species:
- Most of theVitis vinifera cultivars have upright growth habits and require that the fruiting zone be located on the upper 180° of the cordon. The majority of the premium wine produced in the world comes from this species of grapes. Wineries pay premium prices for high quality vinifera grapes. In many premium wine grape regions, the need to restrict crop sizes following mechanical pruning is paramount. These concerns become even greater in regions of the world where there are short growing seasons and potential for winter injury. Producers have to go to extreme hand thinning measures to reduce crop loads, to ensure maturity and maximize winter hardiness. In both cases, the need for cluster and/or berry thinning is necessary to adjust the fruit load to the capacity of the vine. The rule of thumb for foliage to fruit ratio for many cultivars has been 10 to 15 square centimeters of leaf to one gram of fruit. Lakso (18) has reported that after the final exposed leaf area/grams reaches about 8-12 cm2 of functional leaf area per gram of fruit, there is little benefit of having additional leaf area. Crop adjustments to ensure the proper leaf-fruit ratios is used in many grape regions of the world and is even enforced by law in some regions.
- Dr. Robert Pool, Cornell University, Geneva, N.Y. (37), has developed a method to estimate crop level to determine the amount of fruit that should be mechanically removed. Assuming the grower knows the number of vines per acre, an estimate of crop weight (lb.) can be calculated. The grower should harvest all fruit from a representative sample (e.g. two post-lengths) at 1200 growing degree-days, or when berries reach 50% of final weight. For ‘Concord’ in NY, Pool has shown that regardless of pruning system, weather, year, or crop level, 50% of final cluster weight will occur at 1200 growing degree days. However, this timing will change for different cultivars and for different grape growing regions. The grower then multiplies the weight of fruit per vine at 1200 degree-days by 2 to determine crop weight per vine at harvest. Then multiply lb./vine by vines per acre and divide by 2000 to arrive at tons/acre. If the estimated crop is above the desired tons/acre for maximum quality for the cultivar or vineyard, the grower can calculate the percent of fruit he needs to remove from each vine to arrive at the desired cropping level. As a rule, machine thinning should be used about 20-30 days following bloom in cool growing regions such as the “grape belt” region of New York.
- Winkler et al. (Text 1974), who wrote one of the most respected texts on viticulture, felt that one approach to this functional leaf/fruit ratio was to leave vines unpruned and control the crop by thinning. However, during this time period, it was not practical or feasible since mechanization of harvest of unpruned vines was not an option. Unlike the French hybrids, most vinifera grapes are only moderately fruitful and normally do not produce fruitful basal buds. Therefore, mechanical thinning and shoot removal of vigor or large size vines becomes more critical, and in most cases and some trellising systems, will need to be combined with mechanical leaf removal (FIGS.34-40).
- Although the Morris-Oldridge complete vineyard mechanization system of the present invention provides the viticulturist with an arsenal of tools, careful use and intelligent implementation of the desired results from each of these tools must be understood for the system to be successful. Adoption of these new completely mechanized systems will mean a more reliable, more stable, and more economical production of premium quality fruit that will be competitive for the local, regional, national and global markets.
- With reference again to FIGS.2-5 of the drawings, an exemplary shoot and fruit thinner in accordance with the present invention generally designated by the
reference numeral 10 is especially adapted for use with Vitis vinifera and French-American hybrid grapes and is shown in use in connection with a high wire single curtain bilateralcordon trellising system 12. - The shoot and

Horizontal member 56 ofsupport platform 14 is made up of twoside pieces horizontal plate 90. Ahitch ball 92 is attached to plate 90 and provides for quick attachment and detachment of the shoot andfruit thinner 10 to and from a hitch tongue 94 extending horizontally from ahorizontal member 96 of avineyard tractor mast 98 such as shown in any one of FIGS. 34, 36, 39, 48, 51, 56, 74, or the like. After the hitch tongue 94 ofmast member 96 is attached to theball 92, thehorizontal plate 90 andhorizontal member 56 ofsupport platform 14 are fixed in position relative to the end ofmast member 96 by, for example, bolts which pass through brackets extending frommember 96 and intoplate 90. - In accordance with the present invention, and as shown throughout the drawings, each of the devices, apparatus, implements, or the like of the present invention preferably utilize a quick disconnect ball hitch mechanism or assembly to facilitate the attachment and detachment of the respective implements or devices to the mast of a vineyard tractor, harvester, or other machinery or equipment. Also, the ball hitch can be used to facilitate the storage of each of the implements, devices, apparatus, and the like by having a storage rack with a plurality of spaced ball receiving hitch ends which are adapted to attach to the ball on the respective implements.
- Although the shoot and
fruit thinner 10 is shown to utilize ahydraulic motor 36 which receives hydraulic fluid fromhydraulic lines 100 operatively connected to a hydraulic system of the tractor or other vineyard equipment (or an anxiallary hydraulic system attached to, for example, the power take off on the back of the tractor) which is used to transport the shoot andfruit thinner 10 through the vineyard and simultaneously drive bothrotary striker units rotary units single motor 36 to drive each of therotary units - The amount of shoot and fruit thinning that is accomplished using the
rotary striker units striker fingers rotary units fruit thinner 10 is moved through the vineyard and along the vine, and combinations thereof. - With reference to FIGS. 4 and 5 of the drawings, the
striker fingers finger receiving sockets radial support members 110 and 112 (see FIGS. 13 and 14). In accordance with the present invention, it has been discovered that a preferred arrangement of striker fingers includes a pair of such fingers placed adjacent one another and with each of the fingers having aflexible core 114 such as a rubber hose, tube, shaft, or the like, covered partially near its base with arigid support 116 such as a metal pipe, tube, or the like. The flexible ends 114 of theadjacent fingers 24 of the finger pair tend to grab foliage, shoots, grape bunches, and the like, during travel of the fingers through the vine. Also, the flexible ends 114 on the fingers allow the ends to bend or give, should they contact a solid item such as a wire, post, brace, stay, trellis member, cordon wire support, cordon, other striker fingers, brushes, brush bristles, or the like. Although it is preferred to use pairs of fingers, especially for fruit bunch removal, it is contemplated that one could use single fingers to, for example, remove foliage, shoots, thin bunches, or the like, or one could use a single finger having a split end to achieve nearly the same result as a pair of adjacent fingers. Further, the pair of fingers may be further supported by attaching them one to the other near their base by, for example, wrapping tape around the base supports 116 of adjacent fingers. This increases the rigidity of the finger pair and increases the amount of foliage or fruit which is removed during use thereof. Each of thefingers sockets - The number and arrangement of the striker fingers is selected to achieve the desired amount of shoot and fruit thinning, leaf removal, and the like. The
rotary striker units motor 36. - The amount of shoot and fruit removal can be adjusted along the travel of a particular row in a vineyard or along a particular vine section to adjust for different physiological stages or conditions of the vine, shoots, fruit, or the like to insure that the shoots and fruit are evenly spaced along the length of the cordon. Also, the rotary striker units may be replaced with brushes or bristles (see FIGS.15-22) or with oval rotary striker units (see FIG. 23) to achieve a desired result. In accordance with a particular example of the present invention, the
rotary striker units fruit thinner 10 each included four respective pairs of striker fingers driven at a rotary speed from 10 to 250 rpm with the fingers of therespective units rotary striker units fruit thinner 10 is about 32 inches from tip to tip having a 10 inch center disk and 12 inch length fingers with one inch of each finger inserted into its receiving socket. Further, each of the fingers is one-half inch in diameter and made of a flexible solid rubber material. It is preferred to use striker fingers having an outer diameter of from about one quarter inch to one inch and varying in length from about 4 to 24 inches. Further, when brush units are used in place of rotary striker units, it is preferred to use a brush unit having a tip to tip dimension of about 20 to 40 inches, preferably 32 inches. Adjustments in shoot and fruit removal depend on cultivar and shoot numbers and the projected or desired fruit load. - Although it is not shown in FIGS.2-5 of the drawings, an automatic height adjustment mechanism or device can be added, for example, to the
guide wheel yoke 70 or one of theheight adjustment members striker fingers guide wheel 28 relative to theplatform 14. For example, a hydraulic cylinder or an electric motor and screw arrangement can be used to automatically adjust the position of the guide wheel relative to the platform from a control lever or mechanism on the tractor. - As shown in FIGS. 6 and 7 of the drawings, and in accordance with another embodiment of the present invention, a shoot and fruit thinner is generally designated by the

The shoot andfruit thinner 140 is similar to the shoot andfruit thinners hydraulic motor 152, a drive chain, and a plurality ofsprockets rotary striker units - With reference to FIG. 9 of the drawings, and in accordance with still yet another embodiment of the present invention, a shoot and fruit thinner is generally designated by
reference numeral 170 and has a substantially identical construction to that of the shoot andfruit thinner 140 of FIG. 8 except that the extension arms are elongated and positioned at different angles to accommodate a California T-trellis 168. The shoot andfruit thinner 170 includesupper arms lower extension arms upper arms trellis 168.

In contrast, the cutting opening of leadingfan unit 552 is circular and similar to theopening 516 of thefan unit 500 of FIGS. 34 and 35. In accordance with one example, the leadingfan unit 552 has acutting blade 594 with a length of about 16 inches while trailingfan unit 554 has acutting blade 626 with a length of 28 inches. Hence, the total effective area of the intake of each of thefan units opening 630 is not circular. - With reference to FIGS. 38 and 38A-38D, each of the adjustable bars or
rods 588 has dependingstuds stud receiving openings 640 and are adapted to receive alocknut 642 for securement in a selected position. The spacing between the rods or bars 588 and the angle of attack of the rods with respect to the vine can be adjusted or varied upon the conditions to provide for more or less leaf and small shoot removal and also to facilitate the guiding of the leaves and shoots to the inlet or cutting openings of the fan units. - With respect to FIGS. 38, 38A, and38B of the drawings, the rods or bars 588 have a substantially rectangular cross-section with the
large portion 592 telescopically receiving at least a portion of thesmall end 590 therein with each of the large and small portions having a flat base which provides for a shearing action between the cuttingblades rods 588. - With respect to FIGS. 38C and 38D of the drawings, it is contemplated that the
rods 588 may have other cross-sections than rectangular. For example, the rods may have a semi-circular cross-section such asrods 644 of FIG. 38C or a triangular cross-section such asrods 646 of FIG. 38D. Each of therods cutting blades - With respect to FIG. 37 of the drawings,
horizontal mast member 96 is shown to have an externalhydraulic cylinder 648 which provides for extension and retraction of a large rectangular section relative to a smaller rectangular section ofhorizontal member 96.

reference numeral 670 and shown to include a plurality of selectively positioned motor driven brush units 672-682 supported from ahorizontal member 684 extending from avertical member 686 of amast 688 attached to the front of atractor 690. Such a single trellis shoot positioner is used to mechanically shoot position the vines to place the canes in proper position for the winter mechanical pruning operation. Shoot positioning is an effective method of improving fruit quality and of exposing the lower node to sunlight to make the basal nodes more productive than under shady conditions. - Shoot positioning has proven particularly effective with large vigorous vines on GDC which have a drooping-shoot growth habit. Also, as soon as the tendrils touch the wire or another cane, they fasten very quickly. Therefore, vines are usually first shoot position just before bloom. Shoot positioning may require a second pass with the mechanical shoot positioner.
- For the GDC system, all vigorous shoots growing between the two cordon wires must be pulled or brushed down in order to maintain two separate foliage canopies. This can be accomplished with the Oldridge shoot positioner of FIGS. 42, 42A,43, and 43A and middle breaker of FIGS. 48 and 49.

Thevertical pruner 2292 of FIG. 70 is similar to thevertical pruner 2290 of FIG. 66, except that thecane grabber 2300 andvertical cutter 2296 are supported from above in a position closer to the ground than that of thecane grabber 2298 and vertical cutter 2294 ofvertical pruner 2290. - With reference again to FIG. 66 of the drawings, the
cane grabber 2298 likecane grabber 2214 of FIG. 64, includesouter housings chain 2308 driven in a counter-clockwise direction by amotor 2310 mounted on aplate 2312 attached tohousing 2302.Plate 2312 is attached to asupport plate 2314 attached to the lower end of avertical support member 2316 the upper end of which is attached to ahorizontal support member 2318 releasably attached to ahorizontal mast member 2320. - The vertical linear cutter, sickle, hedger, or the like2294 includes an
elongate cutting bar 2322 and a parallel deflector or guide roller 2324 supported by avertical support member 2326 the upper end of which is pivotally attached to ahorizontal support member 2318. Aspring 2328 having one end attached to a member extending fromhorizontal support member 2318 and the other end attached tovertical support member 2326 allows the vertical pruner 2294 to trip rearwardly should the deflector roller or sickle contact an immovable or uncuttable object. Vertical pruner 2294 further includes ahydraulic motor 2330, adrive link 2332, and adrive bracket 2334 attached to a movable set of cutting teeth. Deflector roller 2324 is supported at its upper and lower ends by brackets orjournals 2336 and 2338. - Vertical pruner or pruning and grabbing
unit 2290 operates in the same fashion asvertical pruner 2210 of FIGS. 64 and 65 and is adapted for dormant pruning as described, for example, in stage chart XII of FIG. 97. - FIGS. 67 and 68 of the drawings, illustrate a modified Smart-Dyson
ballerina trellising system 2350 having the shoot growth from the top canes trained upward and the shoot growth from the bottom canes trained downward. The upward shoot growth is hedged to prevent an umbrella-like canopy from developing. Upward shoot growth is held in place by two pairs ofcatch wires vertical posts 2356. The downward growth is not hedged and is allowed to develop an umbrella-like canopy similar to a bilateral cordon. Hence, the upper half (40 inches, 1.02 m) is treated as Vertical Shoot Positioned (VSP) while the lower half (48 inches, 1.2 m) is treated as bilateral trellising systems. The Smart-Dyson Ballerina trellis 2350 is modified from that described in an article by Dr. Richard Smart, the Australian Grape Grower and Winemaker, May 1994,pages 27 and 28. The Smart-Dyson Ballerina trellis has two fruiting zones each approximately within 14 inches above and below the cordon. - The Smart-Dyson Ballerina trellis system was developed by Dr. Richard Smart of Port Macguaire, Australia, and John Dyson of New York. This system was designed to manage extremely high vigor vinifera vines to obtain fruit shoot balance and produce both high yields and quality. The advantage of this modified Smart-Dyson system is the “Ballerina” that has a single cordon with spurs at 48 inches or 1.2 m. The spurs that are on the lower part of the 180° of the cordon forms the lower balerina and the upper spurs form the vertical shoot position part of the system. The lower part of the Smart-Dyson Ballerina system is mechanized in the same manner as shown with respect to the bilateral cordon system. The upper part of the system is trained utilizing the equipment shown for use with vertical shoot position systems.
- With reference to FIG. 69 of the drawings, a
leaf removal unit 2360 is shown in operation in connection with the upper half of a Smart-Dyson ballerina system. Theleaf removal unit 2360 of FIG. 69 is similar to theleaf removal unit 500 of FIG. 34 and includes a fan unit 2362 substantially identical to thefan unit 552 of FIGS. 36 and 37. Leaf remover orunit 2360 includes the single vertically and angularly adjustable blade and fan unit 2362 adapted for cleaning one side of a standard vertical, movable catch wire trellising system, for example, the upper half of a Smart-Dyson ballerina trellising system. Fan unit 2362 includes afan blade 2364, afan housing 2366, an intake contacted to a conicalcutting blade housing 2368, and adischarge 2368 at the lower end of thehousing 2366. Acutting blade 2370 is located in thecutting blade housing 2366 behind a plurality of adjustable length bars orrods 2372 which pass across a circular fan intake opening in a cowling orcover plate 2374 having abent forward surface 2376. The bars orrods 2372 are spaced a sufficient distance apart to allow leaves or small shoots to enter the fan intake and to be cut by theblade 2370 or by being sheared between the rods and the blade.Fan blade 2364 andcutting blade 2370 are mounted on adrive shaft 2378 which is rotatably driven by ahydraulic motor 2380 and supported by a pair of spacedshaft bearings 2382. - The fan unit2362 of
leaf remover 2360 is vertically and pivotally supported by spacedvertical support members 2384 adjustably attached to ahorizontal support member 2386 which is releasably attached to ahorizontal mast member 2388. The angle of the fan and blade unit 2362 is selected by adjusting the relative position of first and secondangle support members member 2390 being attached tohorizontal support member 2386 and the lower end ofmember 2392 being pivotally attached to the upper end offan housing 2366. Likefan unit 500 of FIG. 34, the vertical position and angle of the fan unit 2362 can be quickly and easily altered or adjusted to accommodate different trellising systems and growth habits. Further, the length adjustable bars orrods 2372 like the rods or bars 588 offan unit 552 andfan unit 554 can be placed at different angles and spaced at selected distance (as shown in FIG. 38) to accommodate differing foliage loads, desired clearance, tractor speed, and the like. - With reference again to FIG. 70 of the drawings,
vertical pruner 2292 is substantially identical tovertical pruner 2290 of FIG. 66 except that thevertical support members cane grabber 2300 andvertical sickle 2296, respectively, have been lengthened in order to prune the lower ballerina section of a Smart-Dyson ballerina trellising system. - As shown in FIG. 71 of the drawings and in accordance with another embodiment of the present invention, a modified dual sickle horizontal cutter is generally designated2400 and shown to include a short length, fixed position
upper sickle 2402 and an elongate, rearwardly trippinglower sickle 2404. Thiscutter 2400 is a highly modified version of a horizontal sickle unit developed and tested by Dr. C. Intrieri of Bologna, Italy. The horizontaldual sickle cutter 2400 is adapted, for example, for trimming all shoots to approximately 15 or 30 inches above the vineyard floor as described in stage charts III, IV, VII, VIII, IX, and XII of FIGS. 88, 89, 92, 93, 94, and 97, respectively. - The short length, fixed angular position
upper sickle 2402 is located above and slightly forwardly of the lower longerhorizontal sickle 2404. Upperhorizontal sickle 2402 includes ahydraulic motor 2406 attached to a plate 2408 which is attached to abase member 2410 on the lower end of avertical support member 2412. Like thevertical support member 2128 of FIG. 61, thevertical support member 2412 is adjustably received in a bracket orcollar 2414 attached to one end of ahorizontal support member 2416 which itself is received in an adjustable support bracket orcollar 2418 attached to asupport platform 2420. Thesupport platform 2420 is releasably attached to ahorizontal mast member 2422 of amast 2424 attached to aframe member 2426 of atractor 2428. Thesupport platform 2420 is releasably attached tohorizontal mast member 2422 via a ball hitch and bolt assemblies. - Upper
horizontal sickle 2402 further includes adrive disk 2430 operatively attached to a drive shaft ofmotor 2406. Adrive link 2432 has one end attached to drivedisk 2430 and the other end attached to adrive bracket 2434 which is attached to a movable set of cuttingteeth 2436. - Lower
horizontal sickle 2404 includes anelongate support member 2438 attached to asupport plate 2440 pivotally attached to the lower end ofbase 2410 ofvertical support member 2412. The pivotal connection betweensupport plate 2440 andbase 2410 includes a torsion spring which allowssupport member 2438 of lowerhorizontal sickle 2404 to trip rearwardly about a vertical axis should the lower horizontal sickle contact an immovable or uncuttable object. More particularly, a single large bumper disk orroller 2442 and plurality of smaller bumper rollers ordisks 2444 are rotatably attached to correspondingcantilever support members member 2438. The rollers ordisks horizontal sickle 2404 to trip rearwardly before such objects can contact cuttingteeth 2450 and cause damage to thelower sickle 2404. The rollers orbumpers teeth 2450. Likesickle 2402,lower sickle 2404 includes a motor and drive linkage for reciprocating the cuttingteeth 2450. - The
unit 2400 includes a plurality of set screws or bolts which make it easy to quickly and easily adjust the vertical height of the upper and lowerhorizontal sickles horizontal sickle 2402 tends to protect the support structure and drive arrangement of the sickles by cutting any canes or vineyard floor growth which would otherwise wrap around or entangle these items. The lowerhorizontal sickle 2404 provides the bulk of the trimming of canes and shoots at a selected distance above the vineyard floor, for example 15 or 30 inches, prior to harvest to facilitate mechanical harvesting using, for example, a harvester such as shown in FIGS. 83, 84, 85, or the like. - With reference to FIG. 72 of the drawings and in accordance with another embodiment of the present invention, a more simplified single unit single bar half-row horizontal cutter generally designated2460 is shown to include an elongate, rearwardly tripping,
sickle 2462 substantially identical to the lowerhorizontal sickle 2404 of dual sicklehorizontal cutter 2400 of FIG. 71. The singlehorizontal sickle unit 2460 of FIG. 72 differs from thedual unit 2400 of FIG. 71 in that it does not include the upper short fixedhorizontal sickle 2402 and does include a forwardly extending arced rod orbar 2464 which serves to direct canes, shoots, and the like toward the cuttingteeth 2466 ofsickle 2462. Thecane guiding bar 2464 is fixed in position relative to supportmember 2468 ofsickle 2462. - As shown in phantom lines in FIG. 72 of the drawings,
horizontal sickle 2462 may be vertically adjusted to a variety of selected vertical positions, for example, 15 inches or 30 inches from the vineyard floor, depending on what trellising system is being trimmed or pruned. For example, trimming of shoots and canes prior to harvest may require the shoots or canes to be trimmed to approximately 30 inches above the vineyard floor as described in stage chart VII of FIG. 92. - With reference to FIG. 73 of the drawings, a double or dual unit full-row horizontal cutter is generally designated2470 and shown to include inner and outer dual sickle
horizontal cutter arrangements horizontal cutter 2400 of FIG. 71 except that the outerdual sickle arrangement 2474 is a mirror image of the inner unit orarrangement 2472 and trails theinner unit 2472. Also, the disk orrollers horizontal sickle 2404 ofunit 2400 of FIG. 71 have been replaced with forwardly and downwardly angling aprons orbumpers guards horizontal cutter 2470 of FIG. 73 is particularly adapted for use with the Minimal pruned, high-wire, bi-lateral cordon, Smart-Dyson Ballerina (and other like trellising systems) can serve to trim or prune both sides of a row along a single pass down the row. In contrast, thehorizontal cutters - The support structure for each of the inner and outer dual sickle
horizontal cutters dual unit cutter 2470 differ from the vertical support structure ofunits outer cutters inner cutter 2472 includes upper and lowerhorizontal sickles base 2484 on avertical member 2486.Vertical member 2486 is attached to asupport assembly 2488 at the lower end of avertical support member 2490. The upper end ofvertical support member 2490 is adjustably received in a collar orbracket 2492 which is pivotally attached to ahorizontal member 2494. Aspring 2496 has one end attached to collar orbracket 2492 and the other end attached to a member extending forwardly fromhorizontal member 2494. Hence,spring 2496 allows the collar orbracket 2492,vertical member 2490, and entireinner cutter 2472 to trip rearwardly and upwardly should theinner cutter 2472 contact an immovable or uncuttable object. Also, lowerhorizontal sickle 2482 ofinner cutter 2472 can trip rearwardly about a vertical axis should bumper orguard 2476 contact an immovable or uncuttable object. - Likewise,
outer cutter 2474 includes an upperhorizontal sickle 2498 and a lowerhorizontal sickle 2500 operatively, attached to abase 2502 on the lower end of asupport member 2504. Themember 2504 is attached to asupport assembly 2506 which is attached to the lower end of avertical support member 2508. The upper end ofmember 2508 is received in a bracket orcollar 2510 pivotally attached to ahorizontal member 2512. Aspring 2514 has one end attached to bracket orcollar 2510 and the other end attached to a member extending forwardly ofhorizontal member 2512.Spring 2514 allowssupport member 2508 andouter cutter 2474 to trip rearwardly and upwardly. - Also, at least lower
horizontal sickle 2500 trips rearwardly about a vertical axis should guard orbumper 2478 contact an immovable or uncuttable object. - Dual unit
horizontal cutter 2470 includes asupport platform 2516 releasably attached to ahorizontal mast member 2518 and supporting first and secondhorizontal members valve structure 2524, and one end of first and secondhydraulic cylinders Support member 2494 ofinner cutter 2472 is telescopically received in and supported byfirst member 2520 whilesupport member 2512 ofouter cutter 2474 is telescopically received in and supported bysecond member 2522.Valve structure 2524 includes control valves for selectively applying hydraulic fluid to each of thehydraulic cylinders support members outer cutters cylinders horizontal cutter 2470 at the end of a row, one may extend the shafts of thecylinders outer cutters cutter 2470 has moved beyond the anchoring posts, the operator can retract the shafts of thecylinders outer cutters - With reference again to FIGS.71-73 of the drawings and reference to stage chart II of FIG. 87, although the trimmers and
pruners - As shown in FIG. 74 of the drawings and in accordance with another embodiment of the present invention, a
tilting mast 2540 is shown to include an expandingvertical section 2542 and an extendinghorizontal section 2544 substantially identical in construction to the masts shown, for example, in FIGS. 64-66, and 69 of the drawings. Thetilting mast 2540 of FIG. 74 differs from the other masts in that thevertical section 2542 can tilt relative to the supporting tractor or vehicle.Tilting mast 2540 includes alower support structure 2546 attached to the forward end of the tractor or vehicle and serving to pivotally support alower end 2548 ofvertical mast section 2542 about a horizontal axis of a bolt orpin 2550.Support structure 2546 includes a lowerhorizontal member 2552 which provides for attachment of one end of acylinder 2554 thereto. Ashaft 2556 extending fromcylinder 2554 is attached by a bolt orpin 2558 tolower end 2548 ofvertical section 2542.Support structure 2546 also includes anupper member 2560 which supports ayolk 2562 which limits tilting movement ofvertical member 2542. As shown in phantom lines, the mast is tilted to the left by extension of theshaft 2556 fromcylinder 2554. Likewise, the mast may be tilted to the right by retractingshaft 2556 incylinder 2554. Although themast 2540 may be tilted from 0 to 30 degrees in either direction, it is preferred to have mast only tilt through 0 to 12 degrees in either direction from vertical to ensure stability of the equipment and tractor or vehicle. Extension and retraction ofshaft 2556 fromcylinder 2554 and resultant tilting ofmast 2540 is controlled by the vehicle operator by, for example, controlling hydraulic fluid to and from thecylinder 2554. - The angularly
adjustable mast 2540 of FIG. 74 is adapted for use on hillsides or sloping vineyards and may also be used on a relatively flat vineyard to tilt equipment such as thinning, pruning, or trimming devices, units, or the like to accommodate particular trellising systems or growth habits. As an example,mast 2540 can be used to tilt equipment relative to the angled arms of a GDC or Y-trellis. - With reference to FIG. 75 of the drawings, a basic Geneva Double Curtain (GDC) training system is shown to include cordon wire supports A, cordon wires B, cordons C, pruning canes D, renewal spurs E, and posts F spaced at 24 feet.
- As shown in FIGS. 76 and 77 of the drawings, and in accordance with another embodiment of the present invention, a modified vertical catch wire trellis or modified Lyre or “U” system adapted for complete or total mechanization of vineyard cultivation, especially in an established vineyard, is generally designated2590 and shown to include first and second
cross arms 2592 and 2594 which pivot respectively aboutbolts brackets collar 2604 adjustably attached to apost 2606. The cross arms flex or pivot aboutbolts cross arm extensions cross arms 2592 and 2594 usingrespective pins - Further, each of the
cross arms 2592 and 2594 support movable and pivotingtubular stakes yokes respective bolts yokes respective cross arms 2592 and 2594 bypins cross arm extensions movable stakes arms 2592 and 2594 increase the versatility and adjustability of the modifiedtrellis 2590. As shown, each of the cross arms include a plurality of openings which allow for adjustment in the positioning of the cross arm extensions and movable stakes. - In accordance with a particular example of the present invention, it is preferred to form the tubular members including the
cross arm extensions movable stakes - With reference to FIGS. 78 and 79 of the drawings and in accordance with another embodiment of the present invention, a modified vertical catch wire system or a modified Lyre or “U” trellis having fixed cross arms is generally designated2650 and shown to include elongate tubular
cross arms cross arms respective bolts pins cross arms tubular member 2664 attached to a collar releasably attached to apost 2668. The modifiedtrellis 2650 includes tubularmovable stakes respective yokes respective bolts movable stakes - The modified
trellis 2650 of FIGS. 78 and 79 as well as the traditional Lyre or “U” system is not flexible and requires a modified harvesting system such as an adaptation of a harvester built by G. DeGolier with twin harvesting heads and a catching system to mechanically harvest both sides of the Lyre or “U” in one pass. Such a modified harvesting machine contains two sets of beaters mounted side by side as shown in FIG. 83. - With reference to FIG. 80 of the drawings and in accordance with another embodiment of the present invention, a modified Lyre or “U” trellis adapted for total or complete mechanization is generally designated2700 and shown to include a modified
U tubular member 2702 attached to the upper end of avertical tubular member 2704 by asupport bracket 2706.Cordons cross bar 2712 of theU member 2702. This allows sufficient space for the operation of all mechanization equipment including shoot and fruit thinner, leaf remover, harvester, and the like. Vertically extendingarms U member 2702 extend upwardly an additional 12 to 36 inches, preferably 24 inches, above a conventional Lyre or “U” trellis. - As shown in FIGS. 81 and 82 of the drawings, and in accordance with another embodiment of the present invention, a modified vertical catch wire anchoring and trellis system is shown to include a modified guide wire anchoring
support unit 2730 adapted to be used at each end of a row having a plurality of modified vertical catch wire system or modified Lyre or “U” trellises 2732. The modified guide wire anchoringsupport unit 2730 and modified verticalcatch wire trellises 2732 allow mechanization equipment to enter the end of the row and facilitate total or partial mechanization of the vineyard. Thetrellis 2732 is similar in construction to thetrellis 2700 of FIG. 80 and includes a modified tubular U member attached to the upper end of apost 2736 by a bracket or support 2738. - The guide wire anchoring
support unit 2730 includes a tubular U member havingvertical members horizontal cross member 2746.Cross member 2746 is attached to the top of a firstvertical tubular member 2748 attached to a secondvertical tubular member 2750 by upper and lower cross braces 2752 and 2754. The ends ofcross bar 2746 are additionally supported bybrace members cross bar 2746 and the other end attached tovertical member 2750. An elongateU-shaped channel member 2760 is attached to the lower end of each ofvertical members wire attachment studs vertical members vertical members chains 2778 on the end of the respective catch wires. Also,chain racks bar 2746 for storage of chains, cables, or the like. Ends ofrespective support wires U member 2740 and under respective cross braces 2756 and 2758 to prevent upward movement thereof. Similarly,central guide wire 2776 is tied around the upper-end ofvertical member 2748 just belowcross bar 2746 and abovecross member 2752. - By burying
cross member 2760 below ground and forming the entire anchoring support unit of sturdy rigid materials such as 3 inch outer diameter, ¼ to {fraction (1/2)} inch thick steel pipe and welding all connections, guidewire support unit 2730 provides sufficient support for anchoring the cordon, guide, and catch wires at each end of a row. Thestuds 2762 andchains 2778 allow the cordon wires and guide wires or catch wires to either be released or loosened prior to mechanical harvesting and thereby reduce possible damage to the wires, trellises, anchors, harvesting equipment, and the like. - With reference again to FIGS.76-81 of the drawings, and in accordance with a particular example of the present invention, it is contemplated that the trellises developed for a total or complete or improved mechanization of the vineyard have a cross bar at approximately 42 inches from the vineyard floor, a cordon located about 10 inches above the cross bar, a first guide or support wire catch located about 14 inches above the cordon, and a second higher support or guide wire catch located 14 inches above the first catch. Thus, each of the
trellises trellises - In accordance with another example of the present invention, the
trellis 2700 of FIG. 80 is made from 1{fraction (1/2)} inch outer diameter by {fraction (3/16)} inch circular metal tubing, has an overall height of about 84 inches, an overall width of about 60 inches, a lower central post extending about 32 inches above the vineyard floor, about 14 inches from the top of the post to the cordon, about another 10 inches from the cordon to the first catch wire clip, about 12 additional inches from the first catch wire clip to the second catch wire clip, and about 14 inches from the second catch wire clip to the third or top wire clip. This system provides at least 32 inches of clearance between the vineyard floor and the cross bar, about 14 inches of fruit zone below the cordon, and about 38 inches from the cordon up to the top wire. - With reference to FIG. 83 of the drawings, a modified full-row grape harvesting machine or harvester adapted for use with the modified Lyre or “U” trellis of FIGS. 80 and 81 is generally designated2800 and shown to include two picking
heads conveyor belt conveyors conveyors harvester units row tractor 2814. - The
harvester 2800 is adapted for over-the-row or full row harvesting and further includesrespective aprons catch plates conveyors aprons harvester 2800 to pass by atrellis 2700. - The picking heads may be similar to the harvesting heads of the G. DeGolier harvester or similar in construction to the thinning heads of FIGS. 53 and 54 of the drawings. Further, each of the picking heads includes opposing sets of beaters, strikers, bow heads, rods, or the like2824 which are shown angled downwardly and offset relative one to the other. Also, the beaters, strikers, bow heads, rods, or the like adjacent the cordon may be eliminated or shortened to prevent damage to the cordon.
- In accordance with the present invention, it is contemplated that the picking heads2802 and 2804 of the
harvester 2800 may be tilted with respect to the vertical and as such accommodate a Y or GDC system. Also in accordance with another aspect of the present invention, it is contemplated that the picking heads 2802 and 2804 ofharvester 2800 in FIG. 83 and pickingheads harvester 3000 in FIG. 85 may be supported in a fashion allowing for hydraulic head adjustment to raise, lower, and/or tilt the picking heads to accommodate, for example, angled uprights, or a wide range of trellising systems. - Also, in accordance with the present invention it is to be understood that the
harvester 2800 may include forward and rearward sets of picking heads on each side thereof for harvesting grape varieties which are difficult to harvest. Also, theharvester 2800 may include differing types of picking heads (FIG. 85) and may have the inner beaters, strikers, and the like removed to accommodate the harvesting of grapes on particular training or trellising systems. - With reference to FIGS. 84, 84A, and84B of the drawings and in accordance with another embodiment of the present invention, a modified half-row, floating, at least vertically shaking, rotating head picker
mechanical harvester 2840 is adapted for use with a Lyre or “U”trellis 2842 modified to include movable cordon wire support, roller, orslide assemblies 2844 for each cordon wire. Theharvester 2840 includes aharvesting unit 2846 mounted on one side of atractor 2848 and is a modified version of the early Cornell concept for harvesting a modified GDC trellis with a single, reciprocating, vertical spiked-wheel. The Geneva Double Curtain (GDC) was a trellising system designed specifically for mechanical harvest employing over-the-row machines fitted with vertical-shaking head pickers as described, for example, in Shaulis, N., E. S. Shepardson, and J. C. Moyer. Grape Harvesting Research at Cornell, N.Y. State Hortic. Soc. Proc., Proc. 105th Meeting, January (1960) and Shaulis, N., E. S. Shepardson, and T. D. Kordan. The Geneva Double Curtain. Bull. 811 N.Y. State Agric. Exp. Sta., Geneva, Cornell Univ. (1967). An early over-the-row harvester equipped with vertical-shaking heads was manufactured in the U.S. by Chisholm-Ryder, and an Italian version was built and extensively tested. One difficulty with the Cornell/Chisholm-Ryder system was keeping the spike-wheel picking heads concurrently aligned along the cordons. The end result was that the early Cornell and Chisholm-Ryder machines never saw extensive commercial production. - The half-
row harvester 2840 of FIGS. 84, 84A, and 84B is shown in use with a modifiedtrellis 2842 which incorporates the movable cordonwire support assemblies 2844 which address the problem of picking head alignment along the cordons. Theharvester 2840 and, more particularly, theharvester unit 2846 includes arigid support structure 2850 which is attached to thetractor 2848, at least one spiked-wheel picking head 2852 including a center tumbler 2854, and a plurality of radially extendingspikes 2856 attached thereto. Thehead 2852 floats or rests upon a vertical shaft and idles or rotates should the spikes contact an object, vine, trellis, or the like. The pickinghead 2852 is supported and driven from underneath by amember 2858 extending upwardly from asupport structure 2860. Theharvester unit 2846 includes a collectingconveyor 2862, across conveyor 2864,aprons catch plates 2870 supported from aframe 2872. - Still further, the
harvester unit 2846 includes an upper awning and a vertically-dependingflexible curtain 2876 which directs any grapes or grape bunches downwardly toward collectingconveyor 2862 along withfish scales 2870 andaprons picking head 2852 shakes thecordon 2878 andcordon wire 2880 at least vertically and thereby causes grapes or grape bunches to fall from the vine and onto theconveyor 2862 where they are fed to crossconveyor 2864 into a single collection system. The fish scales 2870 pivot at least rearwardly and thecurtain 2876 is flexible, for example, having elongate vertical cuts or slits therein allowing portions to flex up and over the vine or trellis and allow the harvester to travel along the row while directing as many of the grapes as possible toward thecollection conveyor 2862. - By incorporating the movable cordon
wire support assemblies 2844 and by relaxing the catch wires, loosening the cordon wires, and taking tension out of the cordons and trunks before harvesting, thespikes 2856 of the pickinghead 2852 remain in proper position underneath the cordon and the cordon wire stays in position to shake the cordon and harvest the grapes while preventing damage to the catch wires, cordon wire, cordon, and trunk of the vine. In accordance with the preferred embodiment, the trunk leading to the cordon has a bend and flexibility of at least 10 inches. - With particular reference to FIGS. 84A and 84B of the drawings, the movable cordon wire support, roller, or
slide assembly 2844 is attached to the interior or exterior of eachvertical member 2882 extending upwardly from across bar 2884 of thetrellis 2842. Typically, conventional Lyre or “U” trellis systems have the cordon wire located inside the trellis, and as such the movable cordonwire support assembly 2844 is mounted as shown in solid lines in FIG. 84A. In new vineyards, it would be preferred to add the movable cordonwire support assembly 2844 on the exterior of the trellis to facilitate mechanization of the vineyard. - Each movable cordon
wire support assembly 2844 includes upper and lowerhorizontal plates vertical channel member 2890 and having respective circular openings near their free end for receiving anelongate bolt 2892 having ahead 2894 and a threadedlower end 2896 adapted to receive anut 2898. The shaft of thebolt 2892 and one edge of thechannel member 2890 form an elongate channel adapted to receive a grooved roller, wheel, slide, or the like 2900 having a central circular throughhole 2902 adapted to receive thecordon wire 2880 therethrough. The roller orwheel 2900 may also include an elongateradial slot 2904 which extends to opening 2902 to allow an existing cordon wire to be inserted through the slot and into theopening 2902. Theslot 2904 is thereafter filled with aplug 2906 which is welded in place to prevent thecordon wire 2880 from coming out ofopening 2902 inroller 2900. - It is preferred that the plates, channel member, and bolt be formed of sturdy rigid metal materials while the roller or
wheel 2900 be formed of a synthetic resin or plastic material which can be either self-lubricating or lubricated to easily slide up and down alongchannel member 2890 andbolt 2892. Additionally, end stops 2908 and 2910 can be added to the interior ofplates wheel 2900. It is preferred that thechannel member 2890 be attached tovertical trellis member 2882 by welding, but it is understood that other means of attachment such as screws or rivets may be used. Ifroller 2900 becomes overly worn or broken, it may be replaced by removingbolt 2892 and inserting a new roller. - With respect to FIG. 84C of the drawings, and in accordance with another embodiment of the present invention, a modified guide wire anchoring
support unit 2920 and modifiedtrellis 2922 including movable cordonwire support assemblies 2940 has substantial structural similarity to that of guide wire anchoringsupport unit 2730 andtrellis 2732 of FIG. 81 except that thetrellis 2922 andanchoring unit 2920 are adapted to easily relax, loosen, or release tension on the guide wires and cordon wires to facilitate mechanical harvesting using, for example, the mechanical harvester of FIG. 84 or 85. More particularly, avertical support member 2924 has been extended and includes a chain catch orhook 2926 and chain catch orhooks vertical trellis members respective cordon wires 2936 and guidewires 2938. -
Trellis 2922 has been modified to include a more rectangular U member, movable cordonwire support assemblies 2940, and aguide wire bracket 2942 atop apost 2944. The guide wire anchoringsupport unit 2920 facilitates the use of mechanization equipment while the chain hooks or catches thereon facilitate the loosening, relaxing, and releasing the tension from the catch wires, cordon wire, trunk, and cordons to provide, for example, at least 10 inches of flexibility in the bend of the trunk as it leads to the cordon. - Although the vine and cordons shown in FIGS. 84B and 84C are shown in a Y-type of cordon configuration, it is to be understood that a cordon which runs in only a single direction along a cordon wire may be used in combination with the movable cordon
wire support assembly 2844. - With reference to FIG. 84D of the drawings and in accordance with another embodiment of the present invention, the half-
row harvester 2840 of FIG. 84 or the full-row harvester of FIG. 85 may include one or more floating, shaking, rotating picking heads 2950 which not only shake vertically under the influence of amotor 2952 and drivearrangement 2954, but also shake or articulate in a horizontal direction under the influence of amotor 2956 and drivearrangement 2958.Picking head 2950 includes acentral tumbler 2960 which supports a plurality ofspikes 2962 and has acentral opening 2964 which accommodates a small diameterupper support shaft 2966 and a large diameterlower support shaft 2968 which telescopically receives the lower end ofupper shaft 2966.Picking head 2950 is free to rotate aboutshafts spikes 2962 contacting objects as the picking head is moved along the cordon. -
Lower shaft 2968 is pivotally connected to asupport yoke 2970 by a bolt orpin 2972. The upper end ofshaft 2966 is attached to apivoting link 2974 by abolt 2976 which passes throughlink 2978,link 2974, andshaft 2966.Link 2974 is pivotally attached to an upper arm 2980 ofyoke 2970 by apin 2982.Yoke 2970 is attached to asleeve 2984 which rides up and down on a fixedvertical member 2986 attached to thesupport structure 2988.Motor 2952 is attached to upper end ofvertical member 2986 and has a projecting drive shaft to which is attached adrive disk 2990 having attached thereto adrive link 2992. The other end of thedrive link 2992 is attached to aplate 2994 onsleeve 2984. Activation of themotor 2952 and rotation of its drive shaft causes resulted rotation ofdisk 2990, reciprocation oflink 2992, reciprocation ofsleeve 2984, reciprocation ofyoke 2970, and vertical reciprocation ofpick head 2950. - Similarly,
motor 2956 has a drive shaft to which is attached a drive disk ormember 2996. Rotation or activation of themotor 2956 causes rotation ofdisk 2996, reciprocation oflink 2978, reciprocation oflink 2974, and resultant translational movement of at least the upper end ofpick head 2950. Hence,pick head 2950 not only shakes vertically but also horizontally and, as such, increases the amount of grapes removed from the vine during harvesting or facilitates grape removal, thereby allowing the harvester to operate at a greater land speed. Also, it is contemplated that a plurality of such picking heads may be used for harvesting grape varieties which are difficult to harvest. - With reference again to FIG. 85 of the drawings, and in accordance with another embodiment of the present invention, an over-the-row, full-row modified spike-wheel
picking head harvester 3000 is shown to include at least first and second picking heads 3002 and 3004 supported within a harvester chassis, over-the-row tractor or modified high clearance-type four-wheel tractor 3006. Theharvester 3000 is adapted for harvesting a modified Lyre or “U”trellis 3008 having movable cordonwire support assemblies picking heads - Further, the
harvester 3000 includesrespective catch conveyors aprons plates conveyors trellis 3008 as the harvester runs down along the row. The fish scales and aprons tend to direct all the grapes or grape bunches that are removed to thecatch conveyors - It is contemplated that the picking heads3002 and 3004 of
harvester 3000 may be the pickingheads 2950 of FIG. 84D which shake not only vertically but also horizontally. Also, theharvester 3000 may include four or more picking heads, front and rear sets, for harvesting difficult varieties. Also, prior to harvest, the catch wires should be relaxed, the vertical wires should be loosened, and if necessary the tension should be slightly relaxed out of the cordon wires to allow the trunk bend to flex at least about 10 inches during harvest. Movable cordonwire support assemblies wire support assembly 2844. - With respect to FIGS.86-97 of the drawings and seasonal charts I-XII which provide exemplary embodiments of vineyard mechanization systems or methods, it is to be understood that when reference is made to a particular figure number in the charts, it is to be understood that reference is being made to an exemplary machine, device, implement, harvester, thinner, pruner, trimmer, comber, unit, or the like, and that other devices which provide a similar result may be used. Also, it is contemplated that partial mechanization system and methods can be gleaned from the charts I-XII and Examples I-XII to follow by merely eliminating one or more steps from the system or method.

- The following are examples of the Morris-Oldridge vineyard mechanization systems or processes in accordance with the present invention.
- Mechanization Activities ofVitis labruscana Grapes (and Other Grapes with Drooping Growth Habits) Trained on Single Curtain Trellis Systems:
-
Step 1. Dormant Pruning - Mechanical prune during the dormant season using the mechanical pruner shown in FIGS.44-47.
- Step 2. Shoot Adjustment
- Use modified mechanical pruner (remove brushes) shown in FIGS.42-47 for touch up pruning and shoot thinner shown in FIGS. 53-55, if needed, to thin shoots when they are 2 to 3″ (5-7.5 cm).
-
Step 3. Shoot Positioning and Fruit Adjustment - At 10% bloom, use mechanical shoot positioner shown in FIG. 41. In accordance with the research conducted by Dr. Robert Pool of Cornell University, approximately 25-30 days post bloom, excess fruit may be removed with the thinning unit shown in FIGS.53-55 (amount and timing is dependent on cultivar, fruit set, crop load, vine size and vigor). To determine the amount of fruit load to retain, it is critical to maintain adequate soil moisture, to optimize fertilization, to control pests and to optimize other critical production factors. Also, in regions with short growing seasons, the number of days after harvest and before frost become a consideration for determining fruit load.
- Step 4. Harvesting
- Use an approved commercial harvester such as a harvester equipped with Quad-rods or bow-rods to remove difficult-to-harvest fruit. This harvesting approach allows for excellent fruit removal and does minimal damage to foliage. A harvester should allow for vines to maintain maximum foliage that is capable of carrying out needed photosynthesis and storage of carbohydrates in the vines until frost and/or leaf drop.
- Mechanization Activities ofVitis labruscana Grapes (and Other Grapes with Drooping Growth Habits) Trained on GDC Trellis and GDC-Like Canopy Systems.
-
Step 1. Dormant Pruning - Use mechanical pruner in FIG. 43. Two of these units can be mounted under an over-the-row tractor (harvester)(FIG. 43A).
- Step 2. Shoot Positioning
- At 10% bloom, use mechanical shoot positioner in FIG. 42 to position shoots. Two of these units can be mounted under an over-the-row harvester, FIG. 42A.
-
Step 3. Fruit Adjustment - After berry set, remove excess fruit using units in FIGS. 71 and 72 (with modifications for half rows). In accordance with the research conducted by Dr. Robert Pool of Cornell University, approximately 25-30 days post bloom, excess fruit may be removed using modifications to thinning unit shown in FIGS.53-55 (amount and timing is dependent on cultivar, fruit set, crop load, vine size and vigor). To determine the amount of fruit load to retain, it is critical to maintain adequate soil moisture, to optimize fertilization, to control pests and to optimize other critical production factors. Also, in regions with short growing seasons, the number of days after harvest and before frost become a consideration for determining fruit load.
- Step 4. Breaking Centers
- Break GDC centers as needed to allow air flow and sunlight into canopy centers using units in FIGS.48-51.
-
Step 5. Harvesting - Use an approved commercial harvester such as a harvester equipped with Quad-rods or bow-rods to remove difficult-to-harvest fruit. This harvesting approach allows for excellent fruit removal and does minimal damage to foliage. A harvester should allow for vines to maintain maximum foliage that is capable of carrying out needed photosynthesis and storage of carbohydrates in the vines until frost and/or leaf drop.
- Mechanization of Minimal PrunedVitis labruscana Grapes (and Other Grapes with Drooping Growth Habits) Trained on Single Curtain Trellis Systems:
