Introduction

International Harvester 806: Standard-Tread Agricultural Tractor

The International Harvester 806 is a standard-tread tractor produced between 1963 and 1967. Belonging to a series that includes the 706 and 1206 models, it was designed as a high-capacity machine for heavy-duty agricultural operations, delivering 105 horsepower.

Engine and Cooling

The tractor is powered by an International Harvester 6-cylinder, liquid-cooled engine with a displacement of 301 cubic inches (4.9 liters). It operates at a rated speed of 2400 RPM. The cooling system features a capacity of 24 quarts (22.7 liters) to maintain thermal stability during intensive field work.

Transmission and Drivetrain

The 806 offers two primary transmission configurations: a standard 8-speed unsynchronized gearbox or a 16-speed partial power shift transmission. The latter includes the Torque Amplifier (TA) system, which allows the operator to shift to a lower speed within any gear without using the main clutch, facilitating transitions under varying load conditions. The tractor features a 4x2 2WD drive system, with a 4x4 MFWD configuration available as an option.

Hydraulics and PTO

The hydraulic system utilizes an open-center design with a total flow capacity of 24 gallons per minute (90.8 liters per minute). Steering is supported by a dedicated hydraulic flow of 9 gallons per minute (34.1 liters per minute). The independent rear power take-off (PTO) is available in 1000 RPM or dual 540/1000 RPM configurations, ensuring compatibility with a broad range of implements.

Dimensions and Chassis

Built on a 91-inch (231 cm) wheelbase, the tractor has an overall length of 153 inches (388 cm) and a width of 106 inches (269 cm). The shipping weight is approximately 8,460 lbs (3837 kg) for gas models and 9,220 lbs (4182 kg) for diesel versions. Front and rear treads are adjustable to accommodate different row spacings and stability requirements.

Conclusion

"With its robust 6-cylinder engine and flexible transmission options, the International Harvester 806 served as a reliable workhorse for mid-to-large scale farming operations in the 1960s, providing the power and hydraulic capacity necessary for primary tillage and heavy implement operation."
