Introduction
International Harvester Farmall 460
The Farmall 460 is a row-crop tractor produced by International Harvester between 1958 and 1963 in Rock Island, Illinois. Designed as a versatile agricultural machine, it belongs to the 560 series lineage and offered significant technical advancements for its era, including power steering and optional torque amplification.
Engine and Performance
The tractor is powered by an International Harvester 6-cylinder liquid-cooled engine with a displacement of 221 cubic inches (3.6 liters). It features an 8.75:1 compression ratio and operates at a rated speed of 1800 RPM. The engine utilizes an oil bath air cleaner to ensure longevity in dusty field conditions. It is available in LP gas configuration, delivering approximately 55 horsepower.
Transmission and Drivetrain
The 460 offers two primary transmission configurations. The standard unit provides 5 forward and 1 reverse gear, requiring the tractor to be stopped for shifting. The optional Torque Amplifier (TA) transmission doubles the capability to 10 forward and 2 reverse gears, allowing for clutchless, on-the-move speed reduction. Both systems utilize IH Hy-Tran oil to maintain internal component health.
Hydraulics and PTO
Equipped with an independent 540 RPM rear PTO, the tractor provides consistent power to implements regardless of ground speed. The hydraulic system includes a 12 gpm (45.4 lpm) pump and a 10-gallon (37.9 L) capacity, supporting two hydraulic valves for external equipment control. The implements are attached via the IH Fast Hitch system.
Chassis and Dimensions
This two-wheel-drive tractor features power steering and differential mechanical disc brakes for controlled operation. It has a wheelbase of 95 inches (241 cm) and a ground clearance of 19.5 inches (49 cm) under the frame, which facilitates work in standing crops. The open operator station provides standard access to controls.
Conclusion
The Farmall 460 is characterized by its adaptability in row-crop operations. While early models faced challenges with the rear-end final drive capacity relative to engine output, the introduction of a redesigned rear assembly in 1959 improved its durability. It remains a notable example of late 1950s American tractor engineering, suited for general farm tasks and row-crop maintenance.

Transmission Information of Farmall, 460
Transmission variants 1
- Tractor must be stopped and clutch used to shift gears. An option "heavy tillage gear" was available to replace the third speed in the transmission. Serial number suffix "CC" indicates this option.
| Transmission | Sliding gear |
|---|---|
| Transmission(optional) | IH Hy-Tran |
| Oil type | IH Hy-Tran |
| Gears | 5 forward and 1 reverse |
| Oil capacity | 40 qts [37.9 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 460 will free-wheel, so it should be disengaged when going downhill or towing the tractor to start it.
