Introduction
Cletrac AD Agricultural Crawler Tractor
The Cletrac AD is an agricultural crawler tractor manufactured in Cleveland, Ohio, USA, between 1937 and 1959. This machine was designed for field operations requiring the specific traction characteristics provided by a track-based drive system.
Engine and Performance
The tractor is powered by a 4-cylinder, liquid-cooled engine with a displacement of 226 cubic inches (3.7 liters). It operates at a rated speed of 1530 RPM. The engine features a bore and stroke of 4.00 by 4.50 inches (102 x 114 mm) and utilizes an oil bath air cleaner. The system is engaged via an electric starter. In terms of power output, the unit provides 30.5 hp (22.7 kW) at the drawbar and 38 hp (28.3 kW) at the belt.
Transmission and Drive System
The drivetrain utilizes a gear-type transmission providing 3 forward gears and 1 reverse gear. Power is delivered to the ground through a crawler system equipped with 12-inch tracks, which allows for operation on varied terrain while maintaining stability.
Dimensions and Operator Station
The machine has a total operating weight of 7950 lbs (3606 kg). It features an open operator station, consistent with the design standards of tractors produced during its era of manufacture.
Conclusion
The Cletrac AD is a mid-range crawler tractor suited for agricultural tasks where high traction and soil surface pressure management are necessary. Its mechanical configuration and track-based propulsion made it a durable tool for land preparation and stationary belt-driven applications throughout its production lifecycle.
