Cub Cadet Lawn tractors by series

In the early 1960s, International Harvester entered the small tractor market with the Cub Cadet. The IH Cub Cadets were heavy-duty garden tractors many components borrowed from the larger Cub tractor, and built at the same factory in Louisville. In 1981, International's Lawn Products Group was sold to MTD in 1981 as the subsidiary Cub Cadet Corporation (CCC) and production moved to a new factory in Brownsville, Tennessee. While initially independent, Cub Cadets began to gain more common components with the other MTD brands and are now a fully integrated part of the MTD line. The Brownsville factory was closed in 2009.
