ABSTRACT:
A self-cleaning track for reducing the accumulation of debris between the moving and non-moving components of an endless track. The inventive device includes a plurality of track pads interconnected to form an endless track. Each track pad comprises at least one grouser member extending between a pair of opposing side members, a cavity within each of the side members, an opening projecting into a side of each side member exposing the cavity, a pair of slots on opposing sides of the side members for pivotally receiving a link member, and a ramp portion projecting into each side member from the a lower portion of the slots. The opening allows debris accumulated within the cavity to escape freely. The ramp portions of the slots allow the debris to descend from the cavity when the track pad is in a substantially upper position along the endless track.
