Introduction
International Harvester 560
The International Harvester 560 is a standard-tread tractor produced between 1958 and 1963. Part of the 660 series, this model was designed as a versatile power unit for agricultural and industrial operations, with 65,982 units manufactured during its production run.
Engine and Performance
The tractor is powered by the International Harvester C-263, a 6-cylinder, liquid-cooled, vertical I-head engine. It features a displacement of 263 cubic inches (4.3 liters) and operates at a rated speed of 1800 RPM. The engine produces 72.5 horsepower and 212 lb-ft of torque at 1100 RPM. It utilizes an oil bath air cleaner and maintains a compression ratio of 8.75:1.
Transmission and Drivetrain
The 560 model offers two primary transmission configurations. The base model features a sliding gear transmission with 5 forward gears and 1 reverse gear. An optional Torque Amplifier (TA) system is available, which provides a clutchless powershift between direct drive and a lower speed, expanding the range to 10 forward and 2 reverse gears. The tractor is configured with two-wheel drive and utilizes independent mechanical disc brakes.
Hydraulics and PTO
The hydraulic system includes a 16-gallon (60.6 L) capacity reservoir. The standard pump provides a flow rate of 12 GPM, with an optional upgrade available to 17 GPM for more demanding implements. The tractor is equipped with two valves and a dedicated 2.5 GPM steering flow. The rear Power Take-Off (PTO) is independent and operates at a standard 540 RPM.
Dimensions and Chassis
The tractor has a wheelbase of 85.5 inches (217 cm) and an overall length of 146 inches (370 cm). With a minimum width of 72 inches (182 cm) and a ground clearance of 15 inches (38 cm), the machine is designed for stability in standard-tread applications. It features an open operator station and is compatible with various tire configurations, including standard agricultural front and rear tires or industrial rear options.
Conclusion
The International Harvester 560 is a reliable, high-torque tractor well-suited for general field work and heavy-duty towing tasks. Its combination of a high-capacity hydraulic system and the flexible Torque Amplifier transmission makes it a versatile choice for farmers requiring consistent power across a range of applications.
