International Harvester Cub Lo-Boy

The International Harvester Cub Lo-Boy is a utility tractor produced from 1955 to 1968. It is very similar to the standard Cub but is about 8 inches shorter due to shorter front end spindles and a rotated final drive. Both models feature the IH "Cultivision" offset engine and steering. The tractor is powered by a 1.0L 4-cylinder liquid-cooled gasoline engine producing 13.4 hp, with a 3-speed sliding gear transmission. It has two-wheel drive, manual steering, and an open operator station. The Cub Lo-Boy features an optional IH Fast Hitch, an independent rear PTO, and an open center hydraulic system. Dimensions include a 62-inch wheelbase, 92-inch length, and a weight of 1620 lbs. It was built in Louisville, Kentucky, USA.
