Introduction
International Harvester 1486 Row-Crop Tractor
The International Harvester 1486 is a row-crop tractor produced between 1976 and 1981 at the Rock Island, Illinois facility. Designed for large-scale agricultural operations, this model delivers 162 horsepower and represents a significant entry in the mid-range heavy-duty tractor segment of its era.
Engine and Performance
The tractor is powered by a liquid-cooled, 6-cylinder engine with a displacement of 436 cubic inches (7.1 liters). It operates at a rated speed of 2600 RPM. The engine cooling system has a capacity of 27 quarts (25.6 liters), and the oil system requires 20 quarts (18.9 liters) for proper maintenance.
Transmission and Drivetrain
The transmission system features a two-speed power shift configuration providing 16 forward and 8 reverse gears. It includes a Torque Amplifier (TA) which allows the operator to perform high/low speed adjustments while the tractor is in motion. Range and gear selection must be made while the machine is at a complete stop.
Hydraulics and PTO
The hydraulic system is primarily an open-center design with a pump flow of 12 gallons per minute (45.4 liters per minute) and a reservoir capacity of 22.5 gallons (85.2 liters). The tractor is equipped with an independent rear PTO offering 540/1000 RPM speeds, engaged at 2300 engine RPM, providing versatility for various implements.
Operator Environment and Mechanical Features
The 1486 features power-assist steering and hydraulic disc brakes for operational control. The standard configuration includes a cab with air-conditioning, though open-station versions with a four-post ROPS structure were also manufactured. It is available in both two-wheel and four-wheel drive variants.
Conclusion
With a total production of 21,117 units, the International Harvester 1486 served as a reliable workhorse for row-crop farming. Its combination of a high-torque 6-cylinder engine, versatile transmission with Torque Amplifier, and optional four-wheel drive makes it a suitable machine for heavy-duty field tasks.
