Total production was 29,077, with an additional 170 high-clearance models.
It was restyled with chrome badging, adding a torque amplifier transmission and a 169-cubic-inch (2,770-cubic-centimetre) engine with a liquefied petroleum gas option, and dropping the option for distillate fuel Variants included the IH 300 utility tractor, and a 300 hiboy model. The Farmall 300 replaced the Super H in 1954, and was produced until 1956. Farmall 300 Farmall 300ġ6.2 miles per hour (26.1 km/h) forward, 3.1 miles per hour (5.0 km/h) reverse The Super H was replaced by the Farmall 300. About 29,000 Super H tractors were produced. In 19, International Harvester produced the Farmall Super H, which featured larger engine displacement of 164 cubic inches (2,690 cubic centimetres) and 32 horsepower (24 kW), along with sealed disc brakes, allowing it to be rated for two 16-inch (41 cm) plows. About 392,000 Hs of all kinds were produced, and sold for between $850 and $1,650. Functional variants were the hiboy HV for high crops,with 30.25 inches (76.8 cm) of clearance, the W-4 with standard tread, the I-4 for industrial use, and the O-4 for orchard use. Versions were produced for gasoline, distillate and kerosene fuels. All Hs had hydraulic lifts.The H was marketed to farmers with 100 acres (40 ha) or more of tilled land. As with the other letter-series IH tractors, the H used a modular design that allowed assemblies to be removed and replaced as units.
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. An optional extended axle allowed widths of up to 100 inches (250 cm). Rear wheels could be adjusted from 44 inches (110 cm) to 80 inches (200 cm) in width to allow for different crop row widths. The top road speed was 17 miles per hour (27 km/h), 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. A gasoline engine was added to the line in 1940. Early distillate and kerosene models started on gasoline and switched to their regular fuels once they were warmed up. The sliding-gear transmission includes six total gears: five forward and one reverse. The H is equipped with a 4-cylinder in-line overhead valve with a 152-cubic-inch (2,490-cubic-centimetre) displacement and a 6- volt, positive ground electrical system with generator, (when so ordered or retrofitted). The H was rated for two 14-inch (36 cm) plows. Styled by Raymond Loewy, it was one of International Harvester's " letter series", replacing the Farmall F-20. Production of all versions lasted until 1963. The original H used an International Harvester C152 4-cylinder in-line engine. The H was incrementally updated with new model numbers as the Super H, 300, and 350, but remained essentially the same machine. It was the most widely produced of International Harvester's " letter series", with approximately 390,000 produced over the 14-year run. The Farmall H is a medium-sized two-plow row crop tractor produced by International Harvester under the Farmall brand from 1939 to 1954. 16.3 miles per hour (26.2 km/h) forward, 2.7 miles per hour (4.3 km/h) reverseįarmall Super H, followed by Farmall 300 and 350, replaced by Farmall 340
