Introduction

International Harvester Farmall 504 Row-Crop Tractor

Produced between 1961 and 1968 in Rock Island, Illinois, the International Harvester 504 is a row-crop tractor designed for mid-range agricultural operations. Delivering approximately 51 horsepower, this machine reflects the engineering standards of the 1960s, prioritizing mechanical reliability and operational versatility.

Engine and Performance

The tractor is powered by a 4-cylinder International Harvester engine with a displacement of 152.1 cubic inches (2.5 liters). The liquid-cooled power plant operates at a rated speed of 2200 RPM. It utilizes an oil bath air cleaner and a 12-volt starting system. The cooling system capacity varies between 15 and 18.6 quarts depending on the configuration, and the engine oil capacity is 5 quarts.

Transmission and Drivetrain

The 504 was offered with two transmission configurations: a standard 5-speed unsynchronized gear transmission with one reverse gear, or a 10-speed transmission featuring a two-speed 'Torque Amplifier' power shift. Both options utilize a 267mm dry disc clutch. The tractor is built on a two-wheel-drive chassis, equipped with differential mechanical disc brakes and optional power-assisted steering.

Hydraulics and Hitch

The hydraulic system provides a total flow of 19 gallons per minute (71.9 lpm), split between a 7 gpm hitch pump and a 12 gpm steering/remote pump. The hydraulic reservoir capacity is 13 gallons. The rear hitch is compatible with Type I implements, with optional Type II and IH Fast Hitch availability, supported by integrated position and draft control systems.

Dimensions and Weight

The tractor features a wheelbase of 90 inches for the tricycle version, with an overall length of 141 inches. The operating weight is 5430 lbs, which can be increased to 8705 lbs when fully ballasted. It is fitted with 6.00-16 front tires and 12.4-38 rear tires, providing a standard stance for row-crop applications.

Conclusion

The International Harvester 504 serves as a durable, mid-sized row-crop tractor. Its combination of mechanical simplicity, adjustable hydraulic flow, and the availability of the Torque Amplifier transmission makes it a versatile choice for historical agricultural tasks requiring precise implement control and reliable power delivery.
