Robert Hesse made this model gas tractor based on the Townsend Tractor design.
Robert made the boiler for his tractor from 16-inch natural gas pipe and the smokestack from a 6-inch piece of pipe that he cut and re-welded. The tanks in front of the wheels are used for fuel and to hide an air tank.
'Left: Robert used a 6 HP Economy engine, and a clutch and 3-speed gear box from a Ford Falcon to power his tractor. '
Above: The red tank on the right is for kerosene that is pressurized and piped to the exhaust to make the tractor smoke like a steam engine.
'Right: Robert converted the engine from hit-and-miss to throttle-governed. By using a flyball governor, as well as the original governor, he can switch back to hit-and-miss while running. '
