Introduction

CO-OP B1 Row-Crop Tractor

The CO-OP B1 is a row-crop tractor manufactured by Cletrac in Cleveland, Ohio, between 1941 and 1942. Designed for agricultural versatility, this two-wheel-drive machine was produced in a total of 7,527 units and remains a notable example of mid-20th-century tractor engineering.

Engine and Performance

The B1 is powered by a liquid-cooled Hercules IXA3 four-cylinder gasoline engine with a displacement of 1.9 liters. It features a 3.00-inch bore and 4.00-inch stroke, a 5.75:1 compression ratio, and an oil bath air cleaner. The engine is rated at 20 horsepower, with the drawbar output measured at 1,400 RPM and belt output at 1,700 RPM. Starting is achieved via a manual system.

Transmission and Drivetrain

The tractor utilizes a gear-type transmission providing three forward speeds and one reverse gear. Power transfer is managed by a 9-inch dry plate clutch. The transmission housing has an oil capacity of 9.5 liters (10 quarts), ensuring lubrication for the internal gear components.

Dimensions and Mechanical Specifications

The B1 features a manual steering system and an open operator station. It rides on a wheelbase of 80 inches (203 cm) with an overall length of 118 inches (299 cm) and a hood height of 55 inches (139 cm). The shipping weight is 2,105 lbs (954 kg), which can be increased to 3,115 lbs (1,412 kg) when ballasted. The machine is equipped with 5.50-16 agricultural front tires and 9-24 agricultural rear tires.

Conclusion

With its compact dimensions and 20-horsepower output, the CO-OP B1 was designed for efficient row-crop cultivation. Its straightforward mechanical layout, including manual steering and a robust gasoline engine, made it a functional tool for agricultural tasks during its production period in the early 1940s.
