Introduction
International Harvester Farmall 756 Row-Crop Tractor
The International Harvester Farmall 756 is a row-crop tractor produced between 1967 and 1971. Part of the IH tractor line, this 85-horsepower model was engineered for diverse agricultural operations, offering both standard gear and power-shift transmission configurations to suit various field conditions.
Engine and Performance
The tractor is powered by an International Harvester C-291, a 6-cylinder liquid-cooled engine with a displacement of 291 cubic inches (4.8 L). It features a bore and stroke of 3.75 by 4.39 inches and operates at a rated speed of 2300 RPM. The engine is designed to handle demanding loads, supported by a dual dry element air cleaner system.
Transmission and Drive
Two transmission options were available for the 756. The standard gear transmission provides 8 forward and 4 reverse speeds. Alternatively, the Torque Amplifier transmission offers a two-speed power shift, allowing for on-the-fly shifts from direct drive to a lower speed, resulting in 16 forward and 8 reverse gears. The tractor is equipped with a dry disc clutch and is available in both two-wheel and four-wheel drive configurations.
Hydraulics and Power Take-Off
The 756 is equipped with an independent rear power take-off (PTO), providing selectable speeds of 540 and 1000 RPM at an engine speed of 2100 RPM. The tractor utilizes independent hydraulic disc brakes for stopping power and hydrostatic power steering to reduce operator fatigue during field work.
Dimensions and Operator Environment
The tractor features a wheelbase of 105 inches and a shipping weight of approximately 8,350 lbs for diesel models. It rides on 6.50-16 front and 15.5-38 rear agricultural tires. For operator comfort, a cab equipped with heating and air conditioning was offered as an optional feature.
Conclusion
The International Harvester Farmall 756 is a robust row-crop tractor designed for versatility. With its multiple transmission configurations and independent PTO options, it remains a capable machine for farmers requiring a balance of power and maneuverability for varied field tasks.
