Introduction
International Harvester Farmall 350 Row-Crop Tractor
The International Harvester Farmall 350 is a row-crop tractor produced between 1956 and 1958 in Rock Island, Illinois. Part of the 300 series, this machine was designed as a versatile solution for mid-century agricultural operations, offering a balance of power and maneuverability.
Engine and Performance
The tractor is powered by the International Harvester C175, a 4-cylinder, liquid-cooled engine with a displacement of 175 cubic inches (2.9 liters). It operates at a rated speed of 2000 RPM, producing approximately 42 horsepower. The engine features a 9.0:1 compression ratio and uses LP gas as its primary fuel source.
Transmission and Drivetrain
Two transmission configurations were available: a standard 5-speed sliding gear transmission or a 10-speed two-speed power shift. The latter incorporates the Torque Amplifier (TA), a system allowing for clutchless shifting between direct drive and a lower, high-torque gear range while in motion, which improves efficiency during varied field tasks. Both systems utilize a dry disc clutch.
Hydraulics and PTO
The Farmall 350 is equipped with an independent rear power take-off (PTO) operating at a standard 540 RPM. This independent system allows the operator to control the PTO engagement separately from the tractor's forward motion, facilitating the operation of mounted implements.
Mechanical and Dimensions
Built on a 92.25-inch wheelbase, the tractor features a two-wheel drive chassis with manual steering, though power steering was offered as an optional upgrade. The operator station is of the open-platform design. The machine allows for significant flexibility in field work, with a rear tread width adjustable from 48 to 93 inches and a ground clearance of 19 inches.
Conclusion
The International Harvester Farmall 350 is a robust, field-proven row-crop tractor suited for general agricultural tasks. Its inclusion of the Torque Amplifier and independent PTO made it a flexible tool for farmers of its era, balancing field performance with operational ease.
