Abstract
A removable track for an annular resilient tire having a plurality of elongated transversely extending traction shoes mounted on a belt at spaced-apart positions along the belt. Each of the shoes has a plurality of raised traction bars at the end portions of the shoes and a central raised traction bar at a central portion of the shoe. The traction bars extend generally in a direction from one end of the shoe to the other end with the end bars being positioned on the shoe at a distance from a side edge less than the distance of the central bar from the side edge to provide a flex area for cleaning of the shoes. The traction bars at the ends of the shoes may include transverse bars to reinforce the ends of the shoes and angular bars at an acute angle to the side edges to provide traction in the lateral direction.

A track for an annular resilient tire comprising a flexible belt, a plurality of substantially rigid elongated shoes extending transversely over axial edges of said belt and being mounted on said belt at spaced-apart positions along said belt, each of said shoes having a belt-engaging surface, a generally flat ground-engaging surface, side edges, end edges, end portions adjacent said end edges, a central portion between said end portions, a plurality of raised end bars positioned on said ground-engaging surface at each of said end portions, a raised central bar positioned on said ground-engaging surface at said central portion and extending generally parallel with said end bars in a direction from one of said end portions to the other of said end portions, said central bar being connected to said end bars by connecting bars, said central bar, said connecting bars and said end bars having generally the same height above said ground-engaging surface, said end bars at each of said end portions extending generally in a direction from one of said end edges to said central portion and the distance between at least one of said end bars and one of said side edges being less than the distance between said central bar and said one of said side edges so that the end portions are reinforced by the end bars and a central flex area is provided between the central bars of adjacent traction shoes for ejecting soil from the track.
