Introduction
International Harvester T-4 Agricultural Crawler Tractor
The International Harvester T-4 is a crawler tractor produced between 1959 and 1964. Designed for agricultural applications requiring high traction, this model provides 36 horsepower through a specialized tracked undercarriage system.
Engine and Performance
The T-4 is powered by the International Harvester C-123, a 4-cylinder, liquid-cooled, vertical L-head gasoline engine. With a displacement of 122.7 cubic inches (2.0 liters) and a compression ratio of 6.8:1, the engine delivers its rated power at 2000 RPM. The unit features a firing order of 1-3-4-2 and requires regular maintenance of valve clearances and spark plug gaps to ensure consistent operation.
Transmission and Drivetrain
The tractor offers three distinct transmission configurations to suit various operational needs: a standard 5-speed gear transmission, a 10-speed two-speed power shift transmission, and a 5-speed shuttle transmission. Power is delivered to the ground via a crawler drivetrain equipped with bull gear final drives and 10-inch tracks, providing the stability and grip necessary for agricultural field work.
Power Take-Off and Hydraulics
The machine includes an optional live rear power take-off (PTO) system. The rear PTO type is rated at 1000 RPM, operating at an engine speed of 2000 RPM. These features allow for the integration of various implements, enhancing the tractor's versatility in the field.
Dimensions and Operator Station
With a base weight of 5,767 lbs (2,615 kg), the T-4 is engineered for durability. The operator station is of an open design, focusing on accessibility and visibility. The tractor was manufactured at International Harvester facilities in Melrose Park, Illinois, USA, and Hamilton, Ontario, Canada.
Conclusion
The International Harvester T-4 is a specialized crawler tractor suited for agricultural tasks where traction and stability are critical. Its range of transmission options and robust mechanical construction make it a capable solution for demanding field operations within its power class.
