The Cockshutt Plow Company had previously imported rebranded Oliver and Allis-Chalmers tractors from the United States.

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.

Starting in 1939, Cockshutt studied designs for a Cockshutt-built tractor, with effort accelerating as World War II and war-related production drew to a close.
