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.
The G was released by John Deere in 1937, and it was a general-purpose row-crop tractor, with enough power to manage three plows. As with most row-crop tractors, the spacing between the rear wheels could be adjusted to suit row spacings. On later models, the front wheels were offered with wide and narrow wheel arrangements. The tractor was equipped with a two-cylinder side-by-side 34-horsepower (25 kW) engine, of 412.5-cubic-inch (6,760 cm3) displacement. [1] [2] Both gasoline and kerosene-fueled versions were available. [3] About 64,000 Model Gs were built at the John Deere factory in Waterloo, Iowa. Sale price[ when? ] was about $2,600. [4]
The G was originally to be the Model F, since A, B, C (the GP), D and E (for stationary engines) had all been used, but Deere wished to avoid confusion with the Farmall F-20 and moved to G, retaining the F-prefix for part numbers. [1]
Early Gs tended to overheat, so a larger radiator was fitted. [1] The G received Henry Dreyfuss styling in 1942 and was designated the GM, as it was considered modernized. The plain G designation was reinstated in 1947, and GN (single front wheel) and GW (wide front wheels) models were produced. [2]
In 1953 the G was replaced by the John Deere 70 with all-new styling. The 70 could be ordered for gasoline, distillate, liquefied petroleum gas, and diesel fuels. [2] Engine power was increased, and the 70 could pull four or five plows. The gasoline starting engine for the diesel engines was updated from a horizontally opposed two-cylinder to a V-4. The diesel was found to be particularly powerful, and sold well. [5] [6] About 43,000 70s were built at Waterloo, at a sales price of about $2,800. [7]
In 1956, the 70 was replaced by the John Deere 720 with freshened up styling. The 720 was the largest two-cylinder tractor to be offered by Deere and the most powerful row-crop tractor of the time. The 720's gasoline engine developed 65 horsepower (48 kW). [2] [8] [9]
In 1958 the John Deere 730 was introduced, but it retained the same powertrain as the 720. An electric start in lieu of the gasoline starting engine was offered for diesel models. Production in the United States ran through 1961, when the tooling was relocated to a plant in Rosario, Argentina, where production continued until 1968. [2] [10] [11]
720s and 730s were produced at the Waterloo plant. 22,925 were manufactured, at a sales price of about $3,700. [12]
A tractor is an engineering vehicle specifically designed to deliver a high tractive effort at slow speeds, for the purposes of hauling a trailer or machinery such as that used in agriculture, mining or construction. Most commonly, the term is used to describe a farm vehicle that provides the power and traction to mechanize agricultural tasks, especially tillage, and now many more. Agricultural implements may be towed behind or mounted on the tractor, and the tractor may also provide a source of power if the implement is mechanised.
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 John Deere Model A is a row crop tractor manufactured by Deere & Company. The A was produced in a wide variety of versions for special-purpose cultivation. It received a styling upgrade in 1939 and electric starting in 1947. With the advent of John Deere's numerical model numbering system, the A became the John Deere 60, and later the 620 and 630, 3010, 3020, 4030, 4040, 4050, 4055, and ended with the 7610.
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 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 Super M, Super M-TA, 400, and 450, 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.
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 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-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 John Deere Model GP tractor was a two-plow, and later a three-plow row-crop tractor produced by John Deere from 1928 to 1935. Initially called the John Deere Model C, the name was changed to GP as a result of difficulties in distinguishing between the Model C and Model D over the telephones of the time. It was intended as a response to the Farmall Regular line of general-purpose tractors produced under the Farmall brand by International Harvester..
The John Deere Model B tractor was a two-plow row-crop tractor produced by John Deere from 1935 to 1952, with direct successors produced until 1960. The B was a scaled-down, less expensive version of the John Deere Model A. It was followed by the updated 50, 520 and 530 models.
The John Deere Model H tractor was a row-crop tractor produced by John Deere from 1939 to 1947.
The John Deere Model M tractor was a two-cylinder row-crop tractor produced by John Deere from 1947 to 1952, with successor models produced until 1960. It was succeeded by the updated 40, 420 and 430 models, as well as the 320 and 330 models that occupied the market positions left vacant by the more powerful 400 series models.
The John Deere Model L tractor was a small one-plow row-crop tractor produced by John Deere from 1937 to 1946.
The John Deere Model R tractor was John Deere's first diesel tractor. A large, heavy tractor, it had fixed wheel widths and was not produced as a row-crop tractor with adjustable axles. The R was followed in the John Deere numbered model series by the John Deere 80, 820 and 830 tractors, which represented evolutionary upgrades to the basic R.
The John Deere Model D tractor was a large standard tractor produced by John Deere from 1923 to 1953. Unlike other John Deere letter-series tractors, it kept the "D" designation throughout production, and never changed to a number designation. The D had the longest model run of any John Deere tractor. It was succeeded by the John Deere Model R.
The Oliver 60 series of row-crop tractors was a product line of agricultural tractors produced from 1940 to 1964 by the Oliver Farm Equipment Company. The 60 series was a four-cylinder follow-on to the six-cylinder Oliver 70. As the 70 was outsold by the less-expensive Farmall A, Allis-Chalmers Model B and John Deere Model B, Oliver introduced the 60 to compete.
The Cockshutt 50 row-crop tractor was a row-crop tractor produced by the Cockshutt Plow Company, from 1953 to 1957. It was the largest of a series of Canadian-produced tractors that started with the Cockshutt 30, and was based on the Cockshutt 40 with a more powerful engine. The 50 was a large four or five-plow tractor for general use. The 50 was sold in the United States as the CO-OP E5.
