Introduction
International Harvester 500 Series Crawler Tractor
The International Harvester 500 is an agricultural crawler tractor produced in Hamilton, Ontario, Canada, between 1965 and 1969. Part of the 500C series, this machine was engineered for demanding field applications requiring the traction and stability provided by a crawler undercarriage.
Engine and Performance
The tractor is powered by the International Harvester C-146, a 4-cylinder, liquid-cooled gasoline engine. With a displacement of 145.3 cubic inches (2.4 L) and a compression ratio of 7.6:1, it generates a gross power output of 47 hp (35.0 kW) at a rated speed of 2000 RPM. The fuel system utilizes a 1-inch carburetor, and the intake air is filtered through a dry element cleaner.
Transmission and Drivetrain
Two transmission configurations were available: a standard 5-speed unsynchronized gear transmission or the International Harvester Torque Amplifier. The latter is a partial power shift system that provides 8 forward and 2 reverse speeds, allowing for on-the-move underdrive shifting. Both systems utilize a 10-inch dry disc clutch to transfer power to the drivetrain.
Steering and Braking
As a crawler-type machine, steering is managed through mechanical clutches, which allow for independent control of the tracks. Stopping is achieved via mechanical contracting band brakes, ensuring reliable control during field operations and maneuvering.
Hydraulics and PTO
The hydraulic system features a standard pump flow of 7 gpm (26.5 lpm), with optional configurations allowing for up to 17 gpm (64.3 lpm). The system can support between 1 and 3 valves depending on the specific application requirements. The rear PTO provides both 540 and 1000 RPM options at an engine speed of 2000 RPM, facilitating the use of various implements.
Conclusion
With a wheelbase of 67 inches (170 cm) and a machine weight ranging from 7,050 to 7,260 pounds, the International Harvester 500 is designed for agricultural tasks where high tractive effort and ground stability are primary requirements.
