Introduction

International Harvester Farmall 806: Row-Crop Tractor

The International Harvester Farmall 806 is a row-crop tractor produced between 1963 and 1967 in Rock Island, Illinois. Part of a significant era in agricultural machinery, this model was designed to provide high power and operational versatility for mid-to-large scale farming operations.

Engine and Performance

The tractor is powered by the International Harvester C-301, a 6-cylinder liquid-cooled engine with a displacement of 301 cubic inches (4.9 liters). Rated at 110 horsepower, this engine is designed for sustained agricultural tasks. It utilizes a two-stage dry air cleaner to maintain performance in dusty field conditions.

Transmission and Drivetrain

Operators have access to two transmission configurations: a standard 8-speed unsynchronized transmission or a 16-speed transmission equipped with the Torque Amplifier (TA). The TA system allows for clutchless shifting to a lower speed within each gear, providing flexibility when navigating varying load requirements. The tractor is a two-wheel drive machine featuring a 12-inch dry disc clutch.

Hydraulics and PTO

The 806 utilizes an open-center hydraulic system with a pump flow of 12 gallons per minute (45.4 lpm) for implements and a separate 3 gpm pump for steering. The rear PTO is independent, offering both 540 and 1000 RPM settings to accommodate a wide variety of secondary equipment. It is compatible with both Type I/II hitches and the IH Fast Hitch system.

Dimensions and Handling

With a wheelbase of 101.2 inches and a width of 110 inches, the machine is engineered for stability in row-crop applications. It features power steering and hydraulic dry disc brakes to ensure maneuverability despite its size. The rear tread is adjustable from 56 to 94 inches, allowing for adaptation to different row spacings.

Conclusion

With 42,957 units produced, the Farmall 806 remains a notable example of 1960s tractor engineering. Its combination of high engine output and the flexible Torque Amplifier transmission makes it a reliable choice for heavy-duty field work and general agricultural transport.
