Michigan Tractor and Machinery (operating as Michigan CAT) is making tracks. The company sells, rents, and services heavy equipment -- primarily Caterpillar equipment -- used by the construction, forestry, and other industries. The firm sells new and used equipment such as tractors, dozers, loaders, backhoes, mini excavators, and graders. Represented manufacturers (other than Caterpillar) include Lee-Boy heavy construction equipment and Genie aerial lifts. The company's Power Systems division sells and rents engines and generators. The company also offers parts and maintenance services. In 2011 Indiana CAT dealer MacAllister Machinery acquired Michigan CAT, which had been founded by Jerrold Frost in 1944.
