ABSTRACT:
An endless tract for a tractor having steerable forward wheels and rear twin wheels on each side in tandem, the endless track received by each pair of rear twin wheels. The track has a plurality of embedded bars or strips, each of which is formed with inwardly directed projections, has the shape of an inverted blunted V and is arranged to be received between the pneumatic tires of the twin wheels. Connected on the outside of the endless belts to the interior bars by bolts are transverse ridges extending across the belt and being profiled so as to be inclined downwardly and forwardly relative to the ground whereby the ridges in operation exert traction in the ground in a downwardly inclined direction, the ridges being made of rubber-like material or steel or both and the inclination of the ridges between 20.degree. and 45.degree. relative to the overlying belt and the ground's surface.
