Introduction

International Harvester 1566 Row-Crop Tractor

The International Harvester 1566 is a row-crop tractor produced by Farmall in Rock Island, Illinois, between 1974 and 1976. As part of the 1468 series, this two-wheel drive machine was designed for large-scale agricultural operations requiring high power output.

Engine and Performance

The tractor is powered by the International Harvester DT-436, a 7.1-liter, 6-cylinder turbocharged diesel engine. It produces a rated power of 183 hp (136.5 kW) at 2600 engine RPM. The cooling system has a capacity of 24.6 liters, while the engine oil capacity is 18.9 liters.

Transmission and Drivetrain

The 1566 utilizes a Torque Amplifier transmission featuring a two-speed power shift. This configuration provides a total of 12 forward gears and 6 reverse gears, allowing the operator to adjust speed and torque to field conditions without stopping. Final drives are of the planetary type.

Hydraulics and PTO

The hydraulic system is an open-center design with a pump flow rate of 12 gpm (45.4 lpm). The tractor features an independent rear PTO operating at 1000 RPM at 2300 engine RPM. Optional valves are available for both front and rear hydraulic requirements.

Dimensions and Operator Station

Built on a 105-inch wheelbase, the tractor has an overall length of 168 inches. The rear tread is adjustable from 66 to 120 inches to accommodate various row spacings. The operator station comes standard as an open platform, with an air-conditioned cab available as an option. Braking is handled by hydraulic wet disc brakes, and the steering is power-assisted.

Conclusion

"With a total production of 7,417 units, the International Harvester 1566 remains a significant model from the mid-1970s. Its combination of a high-horsepower turbocharged engine and a flexible transmission makes it suitable for heavy-duty traction and row-crop applications."
