The Cub Cadet brand began as International Harvester's garden tractor line, which was sold to MTD in 1981. In 1993, Mitsubishi compact tractors were imported into North America under the Cub Cadet brand. In 2006, MTD and Yanmar entered an agreement to sell Yanmar compact tractors under the Cub Cadet Yanmar brand. The agreement with Yanmar was modified in 2011, and Yanmar America assumed full control over the tractors. At that time the Cub Cadet name was dropped from compact tractors.
