International Harvester Cub

The International Harvester Cub was produced from 1964 to 1979 by International Harvester in Louisville, Kentucky, USA. It featured a 13 hp gasoline 4-cylinder engine with a 3-speed sliding gear transmission. The Cub's PTO ran counter-clockwise at full engine speed, making it incompatible with standard PTO-driven equipment. The tractor had a two-wheel drive with manual steering and differential mechanical drum brakes. It had an open operator station and was compatible with various attachments including mower decks, blades, and front-end loaders. The Cub was known for its compact size and versatility on small farms.
