Introduction
Caterpillar D2 Crawler Tractor
The Caterpillar D2 is an agricultural crawler tractor produced in Peoria, Illinois, USA, between 1938 and 1957. Designed for heavy-duty field work, this machine features a tracked propulsion system and a liquid-cooled diesel engine, establishing its reputation for durability in agricultural applications.
Engine and Performance
The tractor is powered by a 4-cylinder Caterpillar diesel engine with a displacement of 252 cubic inches (4.1 L). It features a liquid-cooling system and a compression ratio of 18.5:1. The engine produces 30 horsepower, with a rated RPM of 1525 for early models and 1650 for later production units. Starting is facilitated by a dedicated gasoline pony motor.
Transmission and Steering
The drivetrain utilizes a gear-type transmission providing 5 forward speeds and 1 reverse speed. Power transfer from the engine is managed by a dry disc clutch. Steering is executed through mechanical clutches, which allow the operator to independently control the tracks for maneuvering the vehicle.
Dimensions and Chassis
As a crawler tractor, the D2 operates on 12-inch wide tracks designed to optimize traction and ground pressure distribution. The operating weight ranges from 7,420 to 8,536 pounds, depending on configuration. The machine is equipped with an open operator station, providing a direct view of the working area.
Conclusion
The Caterpillar D2 is a classic crawler tractor suited for agricultural tasks requiring high traction and steady pulling power. Its robust mechanical design and straightforward operation have made it a staple in historical agricultural machinery collections and a documented example of mid-20th-century engineering.
