Introduction
International Harvester 350 Utility Tractor
The International Harvester 350 is a utility tractor produced between 1956 and 1958 at the company's facility in Rock Island, Illinois. Designed as a versatile agricultural machine, it belongs to the 300 series of tractors and was marketed as a reliable solution for various farming operations.
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 and features a compression ratio of 9.0:1. The cooling system has a capacity of 16 quarts (15.1 liters).
Transmission and Drivetrain
The 350 offers two transmission configurations: a standard 5-speed sliding gear transmission or a 10-speed two-speed power shift transmission equipped with the Torque Amplifier. The Torque Amplifier allows for clutchless shifting between direct drive and a lower speed range, effectively increasing torque and reducing ground speed on the move. Both options utilize a dry disc clutch.
Hydraulics and Hitch
The hydraulic system is an open-center type with a capacity of 3.4 gallons (12.9 liters) and supports 1 to 3 valves for implement control. It is designed to work with the IH Fast Hitch system, which facilitates the attachment of specialized implements.
Mechanical and Dimensions
This two-wheel-drive tractor features disc brakes and is available with either manual or optional power steering. The wheelbase measures 75 inches (190 cm) for the utility model, with a total length of 119 inches (302 cm). The machine's weight varies by configuration, ranging from approximately 4,595 lbs (2084 kg) for the gas utility version to 4,655 lbs (2111 kg) for the diesel utility version.
Conclusion
The International Harvester 350 is a mid-range utility tractor suited for general agricultural tasks, offering operators the flexibility of the Torque Amplifier system and a robust chassis design typical of the late 1950s production era.
