The Farmall A was built by International Harvester from 1939 to 1947 in Chicago, Illinois, USA and Louisville, Kentucky, USA.

Model History

For Company history see
Main article: International Harvester

The new McCormick-Deering Farmall letter-series wheel tractors introduced in 1939 included the Farmall A, Farmall B, Farmall H, and Farmall M. All had beautiful new styling by industrial designer Raymond Leowy and followed the theme set with the International TD-18 crawler in 1938 and carried through to all International Harvester tractor models through the late 1950s.

The Farmall A was an all-new offset design. The frame, engine, and drive train were offset to the left and the driver’s seat and controls were offset to the right to give the driver an unobstructed view of the ground and the crop being cultivated. International promoted this as its “Culti-Vision” design. The A was rated to pull a 1-bottom plow (singe furrow plough -UK) or cultivate one row. The engine was the same size as that of the old F-14 (113 ci) but was a revised design that would be in production for many years. Only distillate versions of the engine were built in 1939 and a high-compression gasoline version was added the following year. The A was available with the pneumatic Lift-All attachment, powered by exhaust gases, for lifting implements. The A was branded "McCormick-Deering Farmall" initially but the name was shortened to "McCormick Farmall" in 1946.

The Farmall A was International Harvesters's answer to the Allis-Chalmers B, which entered pilot production in 1937 and full production in 1938. The B was also a small 1-plow tractor and it resembled the Farmall A but lacked the offset design. Although the B sold very well, the Farmall A quickly overtook it. When running on gasoline the Farmall A had slightly more power and it had a 4-speed instead of 3-speed transmission. Allis-Chalmers put a larger engine in the B in 1943, but International Harvester responded in 1947 with an improved Farmall Super A.
