Farmall M
Row crop tractor
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.
Description and production
Styled by Raymond Loewy, it was one of International Harvester's "letter series", replacing the Farmall F-30. The M was rated for three 14-inch (36 cm) moldboard plows, commonly called a three-bottom plow.
The M was one of the most-widely produced of International Harvester's "letter series", with 270,140 produced over the 13-year run. The M was equipped with an International Harvester C248 inline overhead valve four-cylinder engine with a 248-cubic-inch (4,060-cubic-centimetre) displacement, and a six-volt electrical system.
This brief starts where responsible research should: with the source description of “Farmall M” as row crop tractor. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as row crop tractor. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Jun 2, 2026. The linked authority identifier is Q23637344. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1939, 1953 and 1954.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
