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.
Styled by Raymond Loewy, [1] [2] 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. [3] [4]
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. The sliding-gear transmission had six total gears: five forward and one reverse. [5]
The M was the larger of the two prominent row crop tractors produced by IH from the late 1930s to the early 1950s, along with the Farmall H and its variants, yet could still use the same implements. [5] As with the other letter-series IH tractors, the M used a modular design that allowed assemblies to be removed and replaced as units. All Ms had hydraulic lifts. Versions were produced for gasoline and distillate fuels. Standard Ms had narrow front wheels on the centerline. Rear wheels could be adjusted on splined axles from 52 inches (130 cm) to 88 inches (220 cm) in width to allow for different row widths. An optional extended axle allowed widths of up to 100 inches (250 cm). [3] [4]
The standard M's purchase price in 1952 was US$2,400(equivalent to $27,537 in 2023). [6]
Beginning in 1941, the M's production coincided with the Farmall MD, a diesel version of the M that would start on gasoline until warmed up sufficiently to switch to diesel. A total of 18,253 MD tractors were produced. In addition, IH produced the Farmall Super M from 1952 to 1954. The Super M featured a larger engine displacement than the standard M, at 264 cu in (4,330 cc). Variations of the Super M, the Super MD (a diesel version of the Super M) and the Super MTA (with a torque amplifier), were produced. In all, IH produced 44,551 Super M tractors, 5,199 Super MD tractors and 26,924 Super MTA tractors. [5] High-clearance variants for farming vegetables and other high crops were also produced, including the Farmall MV and the MDV (diesel), as well as a standard front version (W-6) and the I-6 industrial tractor. Industrial tractors had fixed wheel widths, different gearing, foot throttles and usually had wide front axles. The M was produced in Britain as the BM. [6]
In the United States, the M was produced in Rock Island, Illinois. Farmall M tractors produced in Britain and Australia were designated the BM/BMD and the AM, respectively. The models produced outside of North America mainly used wide front axles instead of the tricycle arrangement popular in the United States and Canada. The British model was produced from 1948 to 1953 in Doncaster, and the Australian model from 1949 to 1954 in Geelong.The M line was replaced by the Farmall 400. [6]

The Farmall 400 replaced the Super M-TA in 1954, and was produced until 1956. It was produced with a four-cylinder 50-horsepower (37 kW) engine with a displacement of 281-cubic-inch (4,600-cubic-centimetre), powering a 10 forward gear and 2 reverse gear torque amplifier transmission. Models were produced for gasoline, diesel and liquefied petroleum gas fuels. Variants included the W-400, with a wide front wheel placement, and the 400 Hi-Clear hiboy model. Total production was 40,957 at Rock Island, Illinois. The 400 was briefly succeeded by the Farmall 450, and then the Farmall 560. [7] [8]
The Farmall 450 replaced the 400 in 1956, and was produced until 1958. The 450 had similar style updates to the corresponding 300/350 upgrades to the H line, and a larger 281-cubic-inch (4,600-cubic-centimetre) gasoline engine. Diesel and LPG models were produced. [9] The McCormick-Deering Farmall B-450 was produced in the United Kingdom from 1958 to 1970, mainly with a wide front axle. [10] About 39,000 450s were produced in the United States. [11]
Comparable products to the M include the Case DC and the John Deere A. [12] Similar offerings to the Super M include the Oliver 77 and the Fordson Major D. [13] The Oliver Super 88, John Deere 70 and Massey 444 were similar to the 400. [14]
Farmall was a model name and later a brand name for tractors manufactured by International Harvester (IH), an American truck, tractor, and construction equipment company. The Farmall name was usually presented as McCormick-Deering Farmall and later McCormick Farmall in the evolving brand architecture of IH.
The Farmall Cub or International Cub was the smallest tractor manufactured by International Harvester (IH) under either the McCormick-Deering, Farmall, or International names from 1947 through 1979 in Louisville, Kentucky.
The Farmall H is a medium-sized two-plow row crop tractor produced by International Harvester under the Farmall brand from 1939 to 1954. It was the most widely produced of International Harvester's "letter series", with approximately 390,000 produced over the 14-year run. It succeeded the Farmall F-20. The H was incrementally updated with new model numbers as the Super H, 300, and 350, but remained essentially the same machine. The original H used an International Harvester C152 4-cylinder in-line engine. Production of all versions lasted until 1963.
The Farmall C is a small two-plow row crop tractor produced by International Harvester under the Farmall brand from 1948 to 1951. The C was developed from the Farmall B as a slightly larger, more versatile implement, raising and moving the B's offset operator seat to the centerline and increasing the wheel size to allow a straight, widely-adjustable rear axle. The C kept the International Harvester C123 engine that had been used in the Super A model. The tractor was heavier and more robust, and featured hydraulic capability from the beginning. The C was incrementally updated with new model numbers as the Super C, 200, 230 and 240, but remained essentially the same machine. The closely related successors to the C were produced until 1962.
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.
The Farmall A is a small one-plow row crop tractor produced by International Harvester under the Farmall brand from 1939 to 1947. The tractor was popular for its set of innovative features in a small, affordable implement. It succeeded the Farmall F-14. The A was incrementally updated with new model numbers as the Super A, 100, 130 and 140, but remained essentially the same machine. Like the smaller Farmall Cub, the Farmall A features a distinctive offset engine, displaced to the left over wide-set front wheels, to allow vision straight ahead. An International Harvester C113 4-cylinder in-line engine was used for early models, increased to an IH C123 with the A-1. The most significant change was the introduction of hydraulics with the Super A. The series was produced until 1973.
The Farmall 60 series tractors are general-purpose row-crop tractors that replaced the larger models of the Farmall letter series beginning in 1958. Produced from 1958 to 1963, the Farmall 460 and 560 tractors represented a modernization of the Farmall H and Farmall M respectively, with higher-horsepower 6-cylinder engines in a restyled body. The heavy general-purpose 660 was sold under the International brand, and was a successor to the McCormick-Deering W series tractors.
The McCormick-Deering W series tractors were a range of standard-tread farming and industrial tractors produced by International Harvester that were derived from the Farmall letter series row-crop tractors of the 1940s and 1950s. Branded by International Harvester as McCormick-Deering products, with the same styling and red paint as the Farmall line, the W series had fixed wheel widths, lower height and wide front axles. Starting in 1956 the W series was integrated into the International Harvester numbering series and the McCormick-Deering branding was dropped.
The Farmall F-30 is a large three-plow row crop tractor produced by International Harvester under the Farmall brand from 1931 to 1939, with approximately 28,900 produced. It was a larger successor to the Farmall Regular, and was replaced in 1939 by the Farmall M as the largest tractor in the Farmall line.
The Farmall F-20 is a medium-sized two-plow row crop tractor produced by International Harvester under the Farmall brand from 1932 to 1939, with approximately 148,000 produced. It replaced the Farmall Regular, and was itself replaced in 1939 by the Farmall H.
The Farmall F-12 is a small two-plow row crop tractor produced by International Harvester under the Farmall brand from 1932 to 1938, with approximately 123,000 produced. An improved model, the two-plow F-14, was produced beginning in 1938 and ending in 1939, when the Farmall letter series tractors were introduced.
The Farmall 340 is a medium-sized row-crop tractor, first produced as part of the Farmall line by International Harvester in 1957. The 340 was a completely new design, unrelated to its predecessor the Farmall 350. Production ran until 1963 for the Farmall model, while production under the International and International Harvester name ran until 1965.
The Farmall 04 series tractors are a family of row-crop tractors with four-cylinder engines, continuing the tradition of four-cylinder engines in Farmall and parent company International Harvester for general-purpose and row-crop tractors. In the early 1960s demand for more power led to the 06 series with six-cylinder engines. Four-cylinder engines were reserved for tractors equivalent to the Farmall H and smaller.
The Farmall 06 series tractors are a family of row-crop tractors with six-cylinder engines, providing greater horsepower than the parallel product line of four-cylinder Farmall 04 series tractors. Until the late 1950s, Farmall and parent company International Harvester tractors used four-cylinder engines for general-purpose and row-crop tractors. Demands for higher performance and greater horsepower led to broader use of six-cylinder engines, with the bulk of International's production moving to the larger engines. The Farmall 806 and 706 were introduced in 1963, with production running to 1967. The Farmall 1206 was introduced in 1965 as the most powerful tractor of its time, using a turbocharged diesel engine. Production of the 1206 also ran until 1967. The 06 series sold well and was regarded as extremely successful.
The Farmall Regular, or just the Farmall, was the first in the Farmall line of general-use row-crop tractors manufactured by International Harvester. The Regular was the first affordable tractor that could be used for plowing, stationary threshing, or cultivating. For most of its product life it was marketed as the "Farmall," with the "Regular" added when the Farmall F-20 and F-30 appeared as its successors. More than 134,000 were sold from 1924 to 1931.
International Harvester produced farm tractors in Australia under both the Farmall and McCormick International brands from 1939 until 1973, after which only the McCormick International brand was used. As in the North American market, the Farmall brand was reserved primarily for row-crop tractors with narrow front wheels. Farmall tractors were sold alongside wide-front McCormick International-badged tractors of the same series. Initial production was mainly from imported parts. The first fully-Australian-made tractors were not built at the Geelong works until 1948.
International Harvester's Farmall brand of tractors were built in the United Kingdom between 1949 and 1970. The Farmall name was applied sparingly to International Harvester's UK products, appearing only as the BM, BMD and B-450.
International Harvester's Farmall brand of tractors were built in France between 1951 and 1964. Initially produced from US-made components, tractors were made at the International Harvester (IH) plant in Saint-Dizier with French parts from 1952. A range of models were produced, many based on the Farmall C, with special narrow-track models for use in vineyards. The offering gradually broadened, with adaptations of IH Germany models. The Farmall brand was phased out in 1964, with subsequent machines bearing the International Harvester brand.
The John Deere Model G tractor was a large three-plow row-crop tractor produced by John Deere from 1937 to 1953, with successor models produced until 1961. It was followed by the 70, 720, and 730.
