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 since 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.
Allis-Chalmers was a U.S. manufacturer of machinery for various industries. Its business lines included agricultural equipment, construction equipment, power generation and power transmission equipment, and machinery for use in industrial settings such as factories, flour mills, sawmills, textile mills, steel mills, refineries, mines, and ore mills.
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 Allis-Chalmers model B was a small agricultural tractor produced by the Allis-Chalmers Manufacturing company from 1937 to 1957. With over 125,000 units produced, the model B became one of the best selling and longest-produced tractors for Allis-Chalmers. Tthe B came in several different variations including the Asparagus B, Potato Special, and the IB industrial tractor, and gave rise to the larger Allis-Chalmers Model C. The Model B was styled by Brooks Stevens, an industrial designer and graphic designer.
The Allis-Chalmers 190XT, also known as the One-Ninety XT, is a row crop tractor produced by Allis Chalmers from 1964 to 1971. The tractors are powered by diesel fuel, gasoline, or LP gas. As its model number implies, it was based on the Allis-Chalmers D19, though it featured many alterations and improvements over the D19. The only difference between the 190 and the 190XT is the addition of a turbocharger on the 190XT diesels. Gasoline-run 190XT's also have a G2800 engine as opposed to the 190's G2500 engine. The stock 190XT is rated at about 93 PTO horsepower.
The Allis-Chalmers D series is a line of tractors made by the Allis-Chalmers Manufacturing Company from 1957 to 1969.
The Allis-Chalmers ED 40 tractor was the last model made by the UK subsidiary of the American Allis-Chalmers Corporation before the plant at Essendine, Rutland, was closed in 1985. Introduced at the Smithfield Show, London in 1960, it retained all the features that rowcrop farmers required but in a manner that made it a universal farm tractor. Only diesel power was available from a four-cylinder ohv of 137.89 cu.ins. indirect injection engine made by the Standard Motor Co, Coventry. As the name may imply, the tractor had about 40 horsepower.
The Model WC was a tractor made by Allis-Chalmers from 1933 to 1948. The WC was designed from its start as a nimble, low-cost, but well-powered row-crop tractor that would make the best use of pneumatic rubber tires, which Allis-Chalmers had just introduced to agriculture in 1932. A successful model at the historical height of row-crop tractor demand, the WC was the best-selling tractor model that Allis-Chalmers ever built.
The Allis-Chalmers Model 6-12 was a farm tractor produced by Allis-Chalmers between 1918 and 1923. Like many other tractors of the era, its model name came from its horsepower ratings, with 6-12 meaning 6 hp at the drawbar and 12 hp at the belt pulley.
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 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 he 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 Oliver 80 series of row-crop tractors was a series of agricultural tractors produced from 1938 to 1963 by the Oliver Farm Equipment Company. The 80 series was a development of the Oliver Hart-Parr industrial tractor, for agricultural use. The initial 80 was rated for three 14-inch plows, making it a medium-sized tractor. By the time the Super 88 development was introduced, it was rated for six plow bottoms, making it a heavy tractor.
The Oliver Super 55 series of utility tractors was developed and produced from 1954 to 1975 by the Oliver Farm Equipment Company to complement the Oliver line of heavy row-crop and standard agricultural tracts. Like row-crop tractors, the wheel track width could be adjusted to conform to crop row spacing, but the front wheels were only offered with a wide track. No narrow front wheel options were offered, making the tractor more stable with front-end loaders.
The Cockshutt 30 row-crop tractor was the first production tractor to be manufactured in Canada. The Cockshutt Plow Company had previously imported rebranded Oliver and Allis-Chalmers tractors from the United States. The Model 30 marked Cockshutt's emergence as a full-line agricultural manufacturer. The tractors were built in Cockshutt's Brantford, Ontario plant. The Model 30 was noted for its introduction of a live power take-off (PTO), the first such accessory that could be operated whether the tractor was moving or stationary. Through the model's production span it was itself resold in the United States as the CO-OP E3 and the Gambles Farmcrest 30.
The Cockshutt 40 row-crop tractor was the second tractor produced by the Cockshutt Plow Company, from 1949 to 1958. Having developed the medium-sized Cockshutt 30, Cockshutt developed the heavier 40, using a six-cylinder engine. The 40 was rated for four plows. It was sold in the United States as the CO-OP E4.
The Cockshutt 20 row-crop tractor was the third tractor produced by the Cockshutt Plow Company, from 1951 to 1958. Having developed the medium-sized Cockshutt 30 and the heavier Cockshutt 40, the 20 was a small two-plow tractor for general use. The 20 was sold in the United States as the CO-OP E2.
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.
The Cockshutt 540 utility tractor was built by the Cockshutt Plow Company, from 1958 to 1962. It was a utility successor to the Cockshutt 20 tractor, capable of operating two or three plows. Following industry trends, the 540 was styled with squared-off lines compared to the streamlined look of previous models.
The Cockshutt 570 row-crop tractor was built by the Cockshutt Plow Company, from 1958 to 1960. It succeeded the Cockshutt 50 heavy tractor in the Cockshutt product line, and was capable of pulling five plows. The new tractor was restyled in accordance with the trend toward squared-off lines, compared to earlier Cockshutt offerings.
