Introduction

International Harvester 786 Row-Crop Tractor

The International Harvester 786 is a row-crop tractor produced between 1980 and 1981 in Rock Island, Illinois. This two-wheel drive machine was designed for general agricultural applications, offering a balance of mechanical simplicity and operational versatility.

Engine and Performance

The tractor is powered by a 6-cylinder, liquid-cooled engine with a displacement of 358 cubic inches (5.9 liters). It operates at a rated speed of 2400 RPM and utilizes a dual dry element air cleaner for filtration. The engine requires an oil capacity of 12 quarts (11.4 liters) and a coolant capacity of 24 quarts (22.7 liters).

Transmission and Drivetrain

The 786 features a transmission offering 16 forward and 8 reverse gears. It incorporates a two-speed power shift Torque Amplifier (TA), which allows the operator to reduce ground speed without using the clutch by pulling the console lever backward. The tractor must be stationary to shift between ranges and gears, excluding the Torque Amplifier function.

Hydraulics and PTO

The hydraulic system is of the open-center type with a total capacity of 22.5 gallons (85.2 liters). The rear power take-off (PTO) is independent and provides dual speeds of 540 and 1000 RPM, utilizing a 1.375-inch shaft. The rear hitch is compatible with category I and II implements.

Dimensions and Handling

With a wheelbase of 101 inches (256 cm) and an operating weight of 11,590 lbs (5257 kg), the tractor provides stability for field operations. It features hydraulic disc brakes and power-assisted steering to assist with maneuverability. The ground clearance is 13 inches (33 cm), and it is equipped with 9.5L-15 front tires and 18.4-34 rear tires.

Conclusion

The International Harvester 786 is a conventional row-crop tractor suited for farmers seeking a reliable, mechanical-shift machine with the added flexibility of a Torque Amplifier for varied agricultural tasks.

Transmission Information of International Harvester, 786

Transmission variants 1

  • The tractor must be stopped to shift the transmission (except the TA). The right-most console lever selects range (high, low, or reverse) and the left lever selects one of four gears. The Torque Amplifier (TA) is on the left side of the instrument panel and may be shifted without the clutch. Pulling back engages the TA, reducing the ground speed. Pushing the lever forward puts the transmission in direct drive (DD) mode.
