INTERNAL COMBUSTION

By the late 1800’s the internal combustion engine began to show promise for a more compact and affordable tractor. The Waterloo Gasoline Traction Engine Company of Iowa and Huber of Marion, Ohio began building tractors that used the new Van Duzen engine. Hart-Parr of Charles City, Iowa introduced their "Old Reliable" 22-45 in 1903. Similar to the OilPull, the Hart-Parr looked much like a steam traction engine and weighed about 10 tons.

Deere & Company got into the tractor business with their purchase of the Waterloo Boy. Its twin-cylinder engine would serve as the foundation of John Deere tractors for decades.
