The A had been restyled earlier in the year but the basic tractor dated back to 1934. When the Farmall H came on the market in mid 1939 its main competition came from the John Deere A. The H was available with the pneumatic Lift-All system for lifting implements. Pneumatic tires were fitted to most Hs and very few were built with steel wheels. The H also used a new 5-speed transmission vs. Its 152 ci ohv 4-cylinder engine running at 1,650 rpm gave about the same amount of power as the the 221 ci 1,200 rpm four of the Farmall F-20 the H replaced. The Farmall H was an all new medium-sized (2-plow) row-crop tractor. 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 new McCormick-Deering Farmall letter-series wheel tractors introduced in 1939 included the Farmall A, Farmall B, Farmall H, and Farmall M.
