Introduction

International Harvester Cub Tractor

The International Harvester Cub is a compact tractor produced between 1947 and 1979, with a later iteration introduced in 1975. Manufactured in Louisville, Kentucky, USA, this machine was designed for small-scale agricultural operations and utility tasks, establishing itself as a long-running series in the International Harvester lineup.

Engine and Performance

The tractor is powered by a 59.5 cubic inch (1.0 L) liquid-cooled engine utilizing a thermosyphon cooling system. It produces 13 horsepower at a rated engine speed of 1800 RPM. The engine features a 6.5:1 compression ratio and an oil bath air cleaner. Maintenance specifications include a 3-quart oil capacity with recommended changes every 120 hours, and a specific firing order of 1-3-4-2.

Transmission and Drivetrain

Equipped with a sliding gear transmission, the Cub provides 3 forward gears and 1 reverse gear. The drivetrain is a standard two-wheel drive configuration. Stopping power is provided by differential mechanical drum brakes. The rear PTO is an independent Cub-10 type, which operates at full engine speed and rotates counter-clockwise, a design feature that requires specific compatible equipment.

Hydraulics and Dimensions

The hydraulic system operates at a pressure of 1200 psi with a total flow capacity of 2.8 gallons per minute and a system capacity of 0.56 gallons. The tractor sits on a 69.25-inch wheelbase, with an overall length of 99.325 inches and a width of 48.25 inches. It is fitted with 4.00-12 agricultural front tires and 8-24 agricultural rear tires.
