ABSTRACT:
A traction unit for the road wheel of a farm tractor, or an analogous vehicle, that includes two idler wheels, located near the front and rear surfaces of the road wheel tire, and an endless flexible belt, trained around the three wheels. Each idler wheel has a pneumatic tire, located in the same plane as the vehicle tire, so that the three tires track along the midplane of the belt. The idler wheels are mounted on a tubular beam, that is rockably suspended from an axle member aligned with the road wheel axle, such that the belt lies essentially flat on the terrain surface, in spite of variations in terrain slope, or contour. The traction unit gives the vehicle added mobility in snow, sand, and other soft terrain.
