Introduction
Cletrac H 12-20 Agricultural Crawler Tractor
The Cletrac H 12-20 is a historical crawler tractor manufactured by Cletrac in Cleveland, Ohio, USA. Produced between 1917 and 1919, this model served as a key link in the evolution of the brand's tractor series, bridging the gap between the R 12-20 and W 12-20 model lines.
Engine and Fuel System
The tractor is powered by a Weidely four-cylinder, liquid-cooled engine with a displacement of 243 cubic inches (4.0 liters). It features a bore and stroke of 3.75 by 5.50 inches (95 x 140 mm). The fuel system utilizes a Kingston carburetor, specifically designed to operate on kerosene, which was a common fuel choice for agricultural machinery of that era.
Transmission and Drive
The H 12-20 employs a gear-type transmission providing two forward speeds and one reverse gear. As a crawler tractor, it utilizes a track-based drive system, which provides enhanced traction and weight distribution compared to wheeled tractors, particularly in challenging soil conditions. The operator station is of an open design, typical for the period.
Performance and Capacity
The tractor is rated with a drawbar power of 12 hp (8.9 kW) for pulling implements and a belt power of 20 hp (14.9 kW) for stationary tasks. In practical agricultural application, the unit was capable of pulling two 14-inch plows, making it a functional primary tillage machine for the small to medium-sized farms of its time.
Conclusion
The Cletrac H 12-20 is a representative example of early 20th-century crawler technology. Its combination of kerosene-fueled power and tracked mobility provided farmers with a versatile tool for heavy field work, firmly establishing its place in the history of agricultural mechanization.
