Abstract
A combination low ground pressure, low turning resistance, and self-cleaning shoe for an articulated endless track used on track-type vehicles is disclosed. The shoe is formed as a rigid body having a sloping forward planar surface and a sloping rearward surface which each run the length of the shoe and which substantially converge toward each other. Projecting from between the forward and rearward surfaces is a third surface, or traction lug. High-floatation planar bearing surfaces are located on each end of the body and each have a portion adjacent to, and of the same width as the traction lug but increase in width with increasing distance from the lug.
