Ford Tractor Division:
Ford's entry into the tractor market with the 9N, designed with Harry Ferguson, marked a significant shift in agricultural mechanization, making powerful, affordable tractors widely available.
9N:
Introduced in 1939, featured the revolutionary Ferguson System (hydraulic lift and 3-point hitch).
2N:
Successor to the 9N (introduced 1942), similar design but some improvements, often less refined than the 8N.
8N:
Introduced in 1947, the most popular model. Featured a more powerful engine, upgraded transmission (with wider gear ratios), improved hydraulics, and updated styling. Key improvements included a higher top gear and a live PTO option on later models.
Production Span:
9N: 1939-1942, 2N: 1942-1947, 8N: 1947-1952 (Ford produced). New Holland continued to use the 8N design and variants post-1952.
Manufacturing Location:
Detroit, Michigan, USA (Ford plants)
Historical Impact Award:
Widely recognized as one of the most influential agricultural machines of the 20th century, enabling small farms to mechanize efficiently.
Durability Rating:
Exceptional durability and longevity, with many units still in operation today.
