Introduction
International Harvester 766
Produced between 1971 and 1976 in Rock Island, Illinois, the International Harvester 766 is a row-crop tractor designed for agricultural operations. This model was engineered to provide a mid-range power solution for field work and implement management.
Engine and Performance
The tractor is powered by the International Harvester D360, a 6-cylinder, liquid-cooled diesel engine. With a displacement of 360 cubic inches (5.9 liters), the engine operates at a rated speed of 2400 RPM. It features a compression ratio of 17:1 and uses a 12-volt electrical starting system.
Transmission and Drivetrain
The 766 offers two transmission configurations. The standard gear transmission provides 8 forward and 4 reverse speeds. Alternatively, the Torque Amplifier (TA) transmission offers a two-speed power shift capability, resulting in 16 forward and 8 reverse speeds. This system allows for on-the-move shifting between direct drive and a lower speed range. Both versions utilize a dry disc clutch.
Hydraulics and PTO
The hydraulic system is of the open-center type, delivering a pump flow of 12 gallons per minute (45.4 liters per minute). The rear power take-off (PTO) is independent and offers dual-speed capability at 540 and 1000 RPM, allowing compatibility with various agricultural implements.
Dimensions and Chassis
Built on a 105-inch wheelbase, the tractor has an operating weight of 10,300 lbs, which can be increased to 11,880 lbs when ballasted. It features two-wheel drive, power steering, and hydraulic dry disc brakes. The operator station is open by design, with an optional cab available for enclosure.
Conclusion
The International Harvester 766 is a conventional row-crop tractor suited for varied field tasks. Its combination of a 6-cylinder diesel engine and flexible transmission options provides the necessary torque and speed control for general farming applications.
