Introduction
Farmall 560 Row-Crop Tractor
The Farmall 560 is a row-crop tractor manufactured by International Harvester between 1958 and 1963. Positioned as a high-capacity machine for its era, it was designed to handle a wide range of agricultural field operations.
Engine and Performance
The tractor is powered by an International Harvester 6-cylinder liquid-cooled engine, with a displacement of 263 cubic inches (4.3 L). It features an I-head configuration and a compression ratio of 8.75:1. Operating at a rated speed of 1800 RPM, the engine delivers approximately 66 horsepower. The cooling system has a capacity of 16 quarts (15.1 L), while the oil capacity is 9 quarts (8.5 L).
Transmission and Drivetrain
The 560 offers two main transmission configurations. The standard model is equipped with a 5-speed sliding gear transmission, requiring the clutch to be used for all gear changes. The optional Torque Amplifier (TA) provides a partial power shift, expanding the range to 10 forward and 2 reverse gears. The TA allows for a clutchless shift-on-the-move to a lower speed; however, as the system free-wheels, operators are advised to disengage it when traveling downhill.
Hydraulics and PTO
The hydraulic system features a total capacity of 16 gallons (60.6 L) with a pump flow rate of 12 GPM (45.4 L/min). It is equipped with 1 to 3 valves to operate external implements. The rear power take-off (PTO) is independent and operates at 540 RPM with a 1.375-inch shaft diameter. The tractor utilizes the IH Fast Hitch system for implement attachment.
Mechanical and Dimensions
Built as a two-wheel-drive machine, the Farmall 560 features manual rack-and-pinion steering, with hydrostatic power steering available as an option. Braking is handled by independent mechanical disc brakes. The tractor has a wheelbase of 96 inches (243 cm) and a total length of 141 inches (358 cm). Various tire configurations are available, including Hi-Clearance models that increase the height and width specifications.
Conclusion
The Farmall 560 represents a significant period in mid-century agricultural engineering. While it provided substantial power for row-crop farming, it is historically noted for early durability issues regarding the final drive, which led to a major factory-sponsored reinforcement program in 1959. It remains a notable machine for collectors and those interested in the evolution of International Harvester equipment.
Production Information of Farmall, 560
- The Farmall 560 experienced problems due to the final drive not being strong enough to handle the power of the engine. An entirely new rear end was offered by International in mid 1959, and the company sponsored a massive replacement program.

Transmission Information of Farmall, 560
Transmission variants 1
- Tractor must be stopped and clutch used to shift gears.
| Type | Sliding gear |
|---|---|
| Gears | 5 forward and 1 reverse |
| Oil capacity | 64 qts [60.6 L] |
Transmission variants 2
- The Torque Amplifier (TA) allows a clutchless shift-on-the-move underspeed for any gear. With the TA lever forward, the TA is disengaged and the transmission is in direct drive (DD) mode. To engage the TA, the lever should be pulled quickly and smoothly to the rear. The TA on the 560 will free-wheel, so it should be disengaged when going downhill or towing the tractor to start it.
