Model historyEdit

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 TD-18 crawler in 1938 and carried out on all International Harvester tractor models through the late 1950s.

The 3-plow Farmall M looked nearly identical to the smaller H. In fact it used the same frame and wheelbase to make interchangeability of mounted implements easier. The M had a much larger engine, a new 248 ci ohv 4-cylinder. The previous 3-plow Farmall, the unstyled F-30, was looking outdated in 1939 compared with styled tractors from other manufacturers. The styled Farmall M, introduced in mid 1939, directly replaced the F-30 and developed about the same hp when running on distillate. The closest competitor, for power, was the still unstyled John Deere G, which also ran on distillate. The Farmall cost $115 less than the G and outsold it by a wide margin. The Allis-Chalmers WC, Avery RO-Trac, and Massey-Harris Challenger were also less powerful than the Farmall. The new gasoline-powered Case DC3 developed about the same hp as the gasoline Farmall M that arrived in 1940. The M was in production a long time, from 1939-1952. By the end of that time it was lagging behind the competition and so International replaced it with the Farmall Super M.
