The International Harvester Auto-Buggy is a 2-cylinder air-cooled motor car that was produced by International Harvester from approximately 1907-1916.
It utilized an opposed cylinder air cooled design that produced 18-20 horsepower, with the engine mounted underneath the car's body. The Auto Buggy had two forward gears and a single reverse gear, and utilized a chain drive system to transmit power to the large "high-wheel" artillery style wheels. Tires were made of solid rubber.
Auto Wagon
The Auto Wagon was a utility version of the Auto Buggy which was fitted out with a panel box body which gave the car an 800-pound freight capacity. A removable rear seat and other accessories such as a top were available optional accessories for an additional price.
