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.
A transmission is a mechanical device which uses gears to change the speed or direction of rotation in a machine. Many transmissions have multiple gear ratios, but there are also transmissions that use a single fixed gear ratio.
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.
Minneapolis-Moline was a large tractor and farm and industrial machinery producer based in Minneapolis and Hopkins, Minnesota, Minnesota known for its Minneapolis-Moline tractor line. It was the product of a merger of three companies in 1929: Minneapolis Steel & Machinery (MSM) which was noted for its Twin City tractors, Minneapolis Threshing Machine Company (MTM) which also produced Minneapolis tractors, and the Moline Implement Company formerly known as the Moline Plow Company. It had manufacturing facilities on Lake Street at Hiawatha Avenue in Minneapolis, MN, in Hopkins, MN and in Moline, IL. Originally known as the Minneapolis-Moline Power Implement Company, and later shortened Minneapolis-Moline Company. Motec Industries was a short lived corporate name change from ca. 1960 until the companies acquisition by White Motor Corporation in 1963. <<prairiegoldrush.com>>
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 D series is a line of tractors made by the Allis-Chalmers Manufacturing Company from 1957 to 1969.
The Model G is a small implement carrier tractor that was made by the Allis-Chalmers Manufacturing Company. At the time of its introduction the Model G was unique for its rear-mounted, Continental N62 engine. It was a four-cylinder engine with a 2⅜ × 3½ inch bore and stroke. The Model G was designed for small farms and vegetable gardeners, and a line of implements specifically designed for it, including ploughs, planters, and cultivators. The design of the Model G allowed for a great view of the belly-mounted implements.
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 John Deere 4020 was an agricultural tractor model made by John Deere from 1964 to 1972. It replaced the nearly identical 4010 that had been introduced with Deere's New Generation series in 1960 and offered a number of improvements over the previous model including more horsepower, heavier rear axles, and a differential lock. The 4020 was produced with three engine options: diesel, petrol, and LPG. The 4020 Diesel has a six-cylinder engine tested at 84 drawbar and 91 PTO horsepower. John Deere's Syncro Range transmission with 8 forward speeds and two reverse speeds was standard, a power shift transmission was optional. Other options included dual rear wheels and an enclosed cab with heat and air conditioning. The 4020 is significant for its great popularity; over 184,000 units were built. It was the most popular tractor of its time.
John Deere 3020 is a tractor that was manufactured by John Deere as part of its New Generation series from 1964 to 1972. The 3020 is nearly identical to the John Deere 3010 model that it replaced. It has a wheelbase of 90 inches, and a fuel capacity of 29 gallons. It was offered with three different engine options including a 3.7L 4-cyl gasoline engine, a 4.4L 4-cyl diesel and a 3.7L 4-cyl LP gas engine all produced by John Deere. The 3020 was rated at 71 horsepower. Transmission options included the standard Synchro Range transmission that offered 8 forward speeds and two reverse speeds and an optional eight speed power shift transmission. Several different tread options were offered by John Deere on the 3020 including, standard, narrow front Row Crop, narrow front Row Crop with "Roll-O-Matic", wide front Row Crop, Row Crop Utility. and Orchard.
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 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 eight-cylinder tractor line or Farmall 08 series was briefly produced near the end of the Farmall product run, in response to pressure to increase horsepower and to match competing brands.
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 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 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.
