The International Harvester Cub Lo-Boy is a compact utility tractor produced between 1955 and 1968 in Louisville, Kentucky.

The tractor is powered by the International Harvester C60, a 59.5 cubic inch (1.0 L) liquid-cooled, 4-cylinder gasoline engine. It produces 13.4 horsepower (10.0 kW) at a rated speed of 1800 RPM. The engine utilizes a 1-3-4-2 firing order and features specific maintenance clearances of 0.013 inches for both intake and exhaust valves.

The hydraulic system is an open-center design providing a pump flow of 2.8 gallons per minute (10.6 lpm) at a pressure of 1200 psi (82.7 bar). Implement attachment is supported by the optional IH Fast Hitch system.
