Farmall H
The Farmall H is a medium-sized two-plow row crop tractor produced by International Harvester under the Farmall brand from 1939 to 1954. It was the most widely produced of International Harvester's "letter series", with approximately 390,000 produced over the 14-year run. It succeeded the Farmall F-20. The H was incrementally updated with new model numbers as the Super H, 300, and 350, but remained essentially the same machine. The original H used an International Harvester C152 4-cylinder in-line engine. Production of all versions lasted until 1963.
Description and production
Styled by Raymond Loewy, it was one of International Harvester's "letter series", replacing the Farmall F-20. The H was rated for two plows.The H is equipped with a 4-cylinder in-line overhead valve with a displacement and a 6-volt, positive ground electrical system with generator,. The sliding-gear transmission includes six total gears: five forward and one reverse. Early distillate and kerosene models started on gasoline and switched to their regular fuels once they were warmed up. A gasoline engine was added to the line in 1940. The top road speed was, but the fifth gear was not enabled on tractors sold with steel wheels, an option present in early models and during World War II, when rubber was rationed.The standard front wheels were closely-spaced nose wheels, with options for a single wheel or a wide front axle. Rear wheels could be adjusted from to in width to allow for different crop row widths. An optional extended axle allowed widths of up to.
The H was the smaller of the two prominent row crop tractors produced by IH from the late 1930s to the early 1950s, along with the Farmall M and its variants, yet could still use the same implements. As with the other letter-series IH tractors, the H used a modular design that allowed assemblies to be removed and replaced as units. All Hs had hydraulic lifts.The H was marketed to farmers with or more of tilled land.
