Ford New Holland 9N Tractor Parts
The Ford New Holland 9N, manufactured from 1939 to 1942, was a revolutionary tractor that brought affordable mechanization to countless farms. Powered by a 2.0L 4-cylinder gasoline engine producing approximately 28 horsepower, its simplicity and reliability made it incredibly popular. With a PTO horsepower around 22, the 9N helped modernize farming practices across America.
The Ford 9N was introduced in 1939 as part of Henry Ford's vision to make tractors accessible to small farmers. It was designed in conjunction with Harry Ferguson and incorporated the innovative Ferguson System three-point hitch. The engine was a Ford-built 120 cubic inch (2.0L) L-head 4-cylinder gasoline engine, rated at around 28 engine horsepower. The transmission was a simple 3-speed manual gearbox. Its PTO delivered around 22 horsepower at 540 RPM. Hydraulic capacity was limited, but sufficient for its intended implements. The 9N featured a Category I three-point hitch, allowing it to use a wide range of implements. This tractor was commonly used for row crop work, light tillage, haying operations, and general farm tasks. While Ford later produced models like the 8N with more power and features, the 9N's affordability and reliability set a new standard and made it a staple on farms across the United States.
