Introduction
Cletrac ED Agricultural Crawler Tractor
The Cletrac ED is an agricultural crawler tractor produced between 1938 and 1941. It represents a specialized segment of mid-20th-century machinery, designed primarily for field operations requiring high traction and stability on uneven or soft terrain.
Engine and Performance
The tractor is powered by a Hercules 4-cylinder diesel engine with a displacement of 226 cubic inches (3.7 liters). Featuring a bore and stroke of 4.00 by 4.50 inches, the engine operates at a rated speed of 1530 RPM and is liquid-cooled to maintain thermal stability during operation. The system utilizes an electric starter for ignition. The machine delivers a claimed drawbar power of 30.5 hp (22.7 kW) and a belt power of 38 hp (28.3 kW).
Transmission and Drive System
The Cletrac ED employs a mechanical gear-driven transmission system, offering 3 forward gears and 1 reverse gear to accommodate various agricultural tasks. As a crawler-type tractor, it relies on an 8-inch track system to distribute its weight effectively, providing superior grip and flotation compared to wheeled counterparts of the same era.
Operator Station and Dimensions
The tractor features an open operator station, consistent with the design ergonomics of the late 1930s. With a total operating weight of 5,950 lbs (2,698 kg), the machine provides a substantial footprint for heavy-duty pulling and field work.
Conclusion
The Cletrac ED is a robust example of pre-war crawler technology. Its combination of a diesel powertrain and track-based propulsion makes it well-suited for agricultural applications where traction is prioritized over speed, remaining a notable model for historical agricultural equipment enthusiasts.
