Description and production

The B was first produced in 1935. It was a general-purpose row-crop tractor, less expensive than the Model A at about two thirds the A's size. As with most row-crop tractors, the spacing between the rear wheels could be adjusted to suit row spacings, and the front wheels were offered with wide and narrow wheel arrangements. The B could work two plows. The tractor was equipped with a two-cylinder side-by-side 17-horsepower (13 kW) engine, of 149-cubic-inch (2,440 cc) displacement. [1] [2] Both gasoline and kerosene-fueled versions were available. [3]

The BN, a single front wheel version, was introduced in 1935, together with a wide front axle version, the BW. The BR standard tread tractor was introduced in 1936 as well, with fixed axle widths and a lower profile, for farming uses that did not involve row-crop cultivation. An orchard version, the BO, and an industrial tractor version, the BI, were also produced. The BR and BO ended production in 1947, with the BI ending production in 1941. Meanwhile the John Deere AR and AO continued until 1952. For compatibility with Model A cultivation accessories, the frame was extended in 1937, referred to as "long-frame" Bs. High-crop versions of all subtypes were offered beginning the same year, with various combinations of letter designations. [1] [2]

The BO-L was a crawler version, produced from 1943 to 1946. [1] [2]

From 1938 a more attractive engine housing and grille, designed by Henry Dreyfuss, enclosed the engine, radiator and steering gear. These were called "styled" tractors. Electric start and lighting were added in 1940. Further updates in 1947 mirrored those of the A, with improvements to operator comfort and a larger engine that produced 15% more power. Tractors produced from 1947 onward were referred to as "late-styled." The B was produced until 1952. [4] [2] [3] All Bs were manufactured at the John Deere factory in Waterloo, Iowa, where 40,057 were built, with a sale price of about $1,900. [5]

John Deere 50

From 1952 the B was replaced by the John Deere 50. with updated styling and a cast frame. Power was increased by 10 percent with the same engine, and a rack-and-pinion rear wheel adjustment was provided, along with live hydraulics and power take-off. Fuel options included gasoline, all-fuel and LP gas. [2] [6] [7] 32,574 50s were built at Waterloo, selling for about $2,000. [8]

John Deere 520

From 1957 the 50 was replaced by the John Deere 520. with new styling. Power output was increased 20%, with a new two-cylinder engine, to the point that the 520 could work three plows. Only row-crop versions were produced, with the same fuels as the 50. [2] [9] [10]

John Deere 530

In 1958 the John Deere 530 was introduced. As with the 520, the 530 was produced only as a row-crop tractor. Fenders were added, with four headlights, and an option was available for power adjustment to rear wheel track width. [2] [11] [12]

Tractor Engineering vehicle specifically designed to deliver a high tractive effort

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, but nowadays a great variety of tasks. 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.

The Massey-Harris Model 101 was a tractor built by Massey-Harris from 1938-1946. Developed under the guidance of James S. Duncan, who gambled corporate losses would drop and won, the 101 introduced the Chrysler L-head inline six. The six would compete with Oliver's straight-six Model 70, while saving money on development of a whole new engine as well as taking advantage of Chrysler's existing parts and service network.

John Deere Model A Row crop tractor

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 styling upgrades in 1938 and 1947 that substantially changed its appearance. Wuith the advent of John Deere's numerical model numbering system, the A became the John Deere 60, and later the 620 and 630.

Farmall H Row crop tractor

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.

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 Super M, Super M-TA, 400, and 450, but remained essentially the same machine. The original M used an International Harvester C152 4-cylinder in-line engine. Production of all versions lasted until 1958.

Farmall C Row crop tractor

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 B 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.

Farmall B Row crop tractor

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.

Farmall A Row crop tractor

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.

McCormick-Deering W series tractors General-purpose crop tractor

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 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.

John Deere Model GP Row crop tractor

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..
