Tractor Trendsetters: Cockshutt 30 Tractor

May 28, 2013

Written by Larry Gay

The Cockshutt Plow Company of Brantford, Ontario, entered the tractor market in 1928 by selling two models of Allis-Chalmers tractors. Cockshutt soon became dissatisfied with this arrangement and switched in 1935 to tractors built by Oliver. The Oliver-built tractors were painted red and yellow and carried the Cockshutt name. During World War II, the Cockshutt officials became concerned that Oliver would not be able to manufacture enough tractors to satisfy the post-war demand for both brands of tractors. After much study and debate, the company proceeded to develop a new design of tractor for sale after World War II. Production of the Cockshutt 30 tractor with an independent PTO started in October 1946. The independent PTO made the Cockshutt 30 a tractor trendsetter.

Cockshutt traced its history back to 1877 when James Cockshutt started the Brantford Plow Works. The company was incorporated in 1882 as the Cockshutt Plow Company. In 1905 the company expanded its line of plows with a patented engine gang plow with 8, 10, or 12 bottoms. Cockshutt soon added other tillage tools, seeding equipment, mowers, rakes, binders, wagons, and carriages to its line. A swather and the No. 7 Pull-Type combine were introduced in the early 1940s. Self-propelled combines were added after the war and the company’s name changed to Cockshutt Farm Equipment Company.

The new Cockshutt 30 tractor was unique with its independent PTO which was controlled by a separate clutch and was not affected by the tractor’s main clutch which controlled the travel of the tractor. This enabled the tractor to supply continuous power to a combine, hay baler, or corn picker at the regular 540-rpm PTO speed while the tractor slowed or stopped. The advantage to this type of PTO was the tractor’s operator could handle varying crop conditions without overloading or plugging the harvesting machine.

The Cockshutt 30, with a 2-3 plow rating, was built as a row-crop tractor with dual front wheels, a single front wheel, or an adjustable wide front axle. It was also available as a standard-tread tractor with a fixed width front axle. The power plant was a 4-cylinder, 153-cubic-inch Buda 4-cylinder gasoline engine and the transmission provided four forward speeds. An optional two-speed gearbox could be added which resulted in eight forward speeds and two in reverse. The Cockshutt 30 tractor was sold in the United States as the CO-OP E-3 and the Farmcrest 30.
