Description and production
Styled by Raymond Loewy, it was one of International Harvester's "List of International Harvester vehicles#Farmall F and Letter Series (1924–1954), letter series", replacing the Farmall F-20. The H was rated for two plows. The H is equipped with a 4-cylinder engine, 4-cylinder in-line overhead valve with a Engine displacement, displacement and a 6-volt, positive ground electrical system with generator, (when so ordered or retrofitted). The sliding-gear Transmission (mechanics), transmission includes six total gears: five forward and one reverse. Early Distillate (motor fuel), 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 .Pripps, pp. 65-69 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.Pripps, pp. 65-69H variants
Versions were produced for gasoline, distillate and kerosene fuels. Functional variants were the hiboy HV for high crops,with of clearance, the W-4 with standard tread, the I-4 for industrial use, and the O-4 for orchard use.Pripps, pp. 65-69 About 392,000 Hs of all kinds were produced, and sold for between $850 and $1,650.Pripps, p. 109Super H
In 1953 and 1954, International Harvester produced the Farmall Super H, which featured larger engine displacement of and , along with sealed disc brakes, allowing it to be rated for two plows. About 29,000 Super H tractors were produced. The Super H was replaced by the Farmall 300.Pripps, p. 95Farmall 300
The Farmall 300 replaced the Super H in 1954, and was produced until 1956. It was restyled with chrome badging, adding a torque amplifier transmission and a 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. Total production was 29,077, with an additional 170 high-clearance models.Pripps, pp. 115-117Farmall 350
The Farmall 350 replaced the 300 in 1956 as an interim measure pending the introduction of the Farmall 340. Built from 1956 to 1958, it was slightly restyled from the 300. A Continental diesel engine was available as an option. The 350 was gradually replaced by the newly designed Farmall 340 beginning in 1957. About 28,000 350s were produced.Klancher, p. 183Pripps, p. 153 The 350 was produced as a utility tractor under the International Harvester 350 label, along with the IH 350 High-Utility high-clearance version, and the IH 350 Wheatland non-row-crop version.Comparable products
Comparable products to the H include the John Deere B, Case Corporation, Case SC, Massey Ferguson, Massey 101 Junior, and the Minneapolis-Moline RTU.Pripps, p. 66 The Oliver Farm Equipment Company, Oliver Super 66, Ford 960 and John Deere 60 were comparable to the 300.Pripps, p. 117 The Case 511B, Massey MF65 and Minneapolis-Moline 445 were comparable to the 450.Pripps, p. 123See also
