Introduction
International Harvester 460 Utility Tractor
Produced between 1958 and 1963, the International Harvester 460 is a two-wheel-drive utility tractor designed for general agricultural applications. It was positioned as a versatile machine offering multiple transmission configurations and a liquid-cooled six-cylinder engine.
Engine and Performance
The tractor is powered by the International Harvester C-221, a 221-cubic-inch (3.6-liter) six-cylinder liquid-cooled engine. It produces 61 horsepower at a rated speed of 1800 RPM. The engine features a compression ratio of 8.75:1 and delivers 180 lb-ft of torque at 1300 RPM. It utilizes an oil bath air cleaner for filtration and is designed to operate on LP gas.
Transmission and Drivetrain
The 460 offers three transmission options to suit varying operational needs. The standard sliding gear transmission provides 5 forward and 1 reverse gear. The Torque Amplifier (TA) configuration expands the range to 10 forward and 2 reverse speeds, allowing for clutchless shifting between direct drive and a lower gear ratio. A Fast Reverse version is also available, incorporating a hand reverser for rapid directional changes without manual shifting.
Hydraulics and PTO
The hydraulic system includes two valves as standard, with a total flow capacity of 12 gpm (45.4 lpm) and an optional configuration providing up to 17 gpm (64.3 lpm). Steering flow is rated at 2.5 gpm (9.5 lpm). The rear power take-off (PTO) is independent and operates at a standard 540 RPM.
Dimensions and Chassis
Built on a 78.7-inch wheelbase, the tractor has an overall length of 129 inches. It features an open operator station with manual steering, though hydrostatic power steering was available as an optional upgrade. The unit is equipped with independent mechanical disc brakes and utilizes the IH Fast Hitch system for implement attachment.
Conclusion
The International Harvester 460 is a utility-focused tractor that served as a reliable workhorse for mid-century agricultural operations. Its combination of a six-cylinder engine, flexible transmission choices, and configurable hydraulic flow makes it a adaptable machine for a variety of field tasks.
