Farmall B

The Farmall B is a small one-plow row crop tractor produced by International Harvester under the Farmall brand from 1939 to 1947. It was derived from the popular Farmall A, but was offered with a narrow set of centerline front wheels instead of the A's wide front axle, allowing two-row cultivation. The operator's seat was offset to the right to allow better forward visibility.

Description and production

Styled by Raymond Loewy,[1][2] it was one of International Harvester's "letter series", with 75,241 produced over the 8-year run. Mechanically identical to the Farmall A from which it was derived, B was rated for one 14-inch (36 cm) plow.[3]

The B is equipped with the A's International Harvester C113 4-cylinder inline overhead valve engine, with a 113-cubic-inch (1,850-cubic-centimetre) displacement. The sliding-gear transmission contains five total gears: four forward and one reverse, transmitted via a portal axle. It was similar to the Farmall A, using the same engine moved back to the tractor's centerline, with a narrow front end, centrally placed, and with the seat offset to the right to preserve some of the A's cultivation visibility. The arrangement allowed two rows to be cultivated.[3] As with other Farmall letter-series tractors, the design featured an integral frame and unitary construction, allowing entire assemblies to be replaced. Rear wheels on all models used a geared portal axle to provide sufficient ground clearance, and could be adjusted in width over a range of 64 inches (160 cm) to 92 inches (230 cm), allowing it to straddle wider rows than the A could.[4][5] Versions were produced for both gasoline and kerosene fuel. About 210,000 As and Bs were produced, selling for between $575 and $1,000.[6]

The B was replaced by the Farmall C in 1948.[7][8]

From 1940 to 1947, International Harvester produced the Farmall BN, with the same engine displacement, but with a rear wheel width adjustment of 56 inches (140 cm) to 84 inches (210 cm) for narrower rows.[4] About 1500 BN tractors were produced.[5]
