The Yanmar was founded in Japan in 1912. The firm has a long history with small diesel engines. The agricultural equipment division of the company was started in 1961. Yanmar entered into an arrangement with John Deere and began building several utility tractor models in the early 1980s for Deere. Yanmar continues to be an engine supplier for Deere's utility tractors. Yanmar entered an agreement with MTD in 2006 to jointly market compact tractors under the Cub Cadet Yanmar name in North America. The arrangement ended in 2011 and Yanmar America became the sold provider for the tractors.
