The Farmall M is a large three-plow row crop tractor produced by International Harvester under the Farmall brand from 1939 to 1953. It was of International Harvester's "letter series". It succeeded the Farmall F-30. The M was incrementally updated with new model numbers as the MD Super M, Super MD Super M-TA, but remained essentially the same machine. The original M used an International Harvester C248 4-cylinder in-line engine. Production of all versions lasted until 1954, when it was replaced by the Farmall 400 which was essentially the same machine with updated sheet metal.
