Introduction
International Harvester TD-20 Crawler Tractor
The International Harvester TD-20 is an agricultural crawler tractor produced between 1958 and 1962 in Melrose Park, Illinois, USA. Designed for heavy-duty traction, it serves as a successor to the TD-18A series, providing substantial power and stability for demanding field and earthmoving operations.
Engine and Performance
The tractor is powered by the International D-691, a 6-cylinder, liquid-cooled diesel engine with a displacement of 11.3 liters. It features a bore and stroke of 121 x 165 mm and operates at a rated speed of 1550 RPM. The engine delivers 134 hp (99.9 kW), providing a drawbar power of 111 hp (82.8 kW) for heavy pulling tasks. The engine utilizes a gasoline-start system with a 12-volt starter and maintains a compression ratio of 15.06:1.
Transmission and Drive
The TD-20 utilizes a gear-type transmission providing 6 forward and 6 reverse speeds. Power is transferred to the drivetrain through a dry disc clutch. The tractor operates on a crawler drive system, utilizing 22-inch tracks to ensure traction and weight distribution across challenging ground conditions.
Mechanical and Dimensions
The unit weighs approximately 32,485 lbs (14,735 kg) and features a wheelbase of 94 inches (238 cm). Braking is managed via contracting band brakes. The operator environment consists of an open station, providing the driver with unobstructed visibility of the work area.
Conclusion
With its significant mass and track-based propulsion, the International Harvester TD-20 is engineered for heavy agricultural applications and land development tasks requiring high drawbar pull and consistent stability in difficult terrain.
