Introduction
Cletrac R 12-20 Agricultural Crawler Tractor
The Cletrac R 12-20 is a historical agricultural crawler tractor manufactured by Cletrac in Cleveland, Ohio, USA. Produced between 1916 and 1917, this machine represents early 20th-century mechanized farming technology, designed for durability and traction in varied field conditions.
Engine and Performance
The tractor is powered by a Buda liquid-cooled engine designed to run on kerosene. The engine features a bore and stroke of 3.50 by 5.125 inches (89 x 130 mm). In terms of output, it provides a claimed 12 hp (8.9 kW) at the drawbar and 20 hp (14.9 kW) at the belt, reflecting its capacity for both pulling implements and driving stationary agricultural equipment.
Transmission and Drive
The R 12-20 utilizes a gear-type transmission offering 2 forward gears and 1 reverse gear. The machine features a crawler drive system, which distributes the tractor's weight over a larger surface area compared to traditional wheels, providing improved traction and stability on soft or uneven terrain. The operator station is of the open type, which was standard for the era.
Operational Capability
Designed for primary tillage tasks, the Cletrac R 12-20 is rated to handle two 14-inch plows. Its configuration as a crawler tractor allows it to maintain consistent performance in conditions where wheel-based tractors of the same period might encounter significant slippage.
Conclusion
The Cletrac R 12-20 is a notable example of early crawler tractor development. With its specific engine configuration and track-based propulsion, it was engineered to meet the demands of farmers requiring reliable pulling power for plowing operations in the early 1900s.
