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 Hopkins, Minnesota. 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 (MTMC) which also produced Minneapolis tractors, and Moline Plow Company. It had manufacturing facilities on Lake Street at Hiawatha Avenue in Minneapolis, MN, in Hopkins, MN and in Moline, IL.
Cockshutt was a large agricultural machinery manufacturer, known as Cockshutt Farm Equipment Limited (1957–1962), based in Brantford, Ontario, Canada.
The Massey-Harris Model 101 was a tractor built by Massey-Harris from 1938 to 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.
Buda Engine was founded in 1881 by George Chalender in Buda, Illinois, to make equipment for railways. Later based in Harvey, Illinois, Buda from 1910 manufactured engines for industrial, truck, and marine applications. Early Buda engines were gasoline fueled. Later, diesel engines were introduced, utilizing proprietary Lanova cylinder head designs, injection pumps and nozzles. These were known as Buda-Lanova diesel engines. Buda Engine Company was acquired by Allis-Chalmers in 1953. The Buda-Lanova models were re-christened "Allis-Chalmers diesel".
The Allis-Chalmers D series is a line of tractors made by the Allis-Chalmers Manufacturing Company from 1957 to 1969. Most of the D-series tractors, except for the D21, had hand-operated, shift-on-the-go oil clutches, commonly referred to as a hand clutch. Allis-Chalmers marketed this arrangement as the "Power Director". This clutch was in low range when pulled back, neutral in the middle, and high range when pushed forward. It could also be ordered as a forward-reverser, called the "Shuttle Clutch". This hand clutch also exists on the D21, but it was not meant for shifting on the go.
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 Oliver 70 series of row-crop tractors was a series of large agricultural tractors produced from 1935 to 1967 by the Oliver Farm Equipment Company. Oliver tractors were know for their powerful engines compared to competitors, and their attention to styling. The Oliver Hart-Parr 70 marked the beginning of a strikingly-styled series of tractors that were produced under both the Oliver and the Cockshutt names. Oliver's emphasis on styling strongly influenced offerings by competing brands such as Farmall and John Deere.
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 90 series of row-crop tractors was a series of agricultural tractors produced from 1937 to 1961 by the Oliver Farm Equipment Company. Beginning with the Hart-Parr 28–44, the series was the most powerful Oliver tractor offering, capable of heavy plowing. Initial development proceeded on parallel lines, with the 28–44 offered with low and high-compression engine options that became the Oliver 90 and 99, respectively. The lines merged with the Super 99, then diverged again with the 950, 990 and 995 models. The series was produced until 1961.
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 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 550 row-crop tractor was built by the Cockshutt Plow Company, from 1958 to 1961. It succeeded the Cockshutt 35 Golden Arrow in the Cockshutt product line, and was capable of pulling two or three plows. The new tractor was restyled in accordance with the trend toward squared-off lines, compared to earlier Cockshutt offerings. Confusingly, the 550 was replaced in 1962 by a different Oliver-built tractor, also branded as the Cockshutt 550.
The Cockshutt 560 row-crop tractor was built by the Cockshutt Plow Company, from 1958 to 1961. It succeeded the Cockshutt 40D4 diesel in the Cockshutt product line, and was capable of pulling four plows. The new tractor was restyled in accordance with the trend toward squared-off lines, compared to earlier Cockshutt offerings.
