ANTI-TOENAILING TRACK SHOE

Abstract:

A machine track includes a track shoe having a first outboard edge and a second outboard edge, and a first set of pin lugs and a second set of pin lugs. A roller pad is positioned between the sets of pin lugs and includes a roller contact surface extending between a first roller pad end and a second roller pad end. The first roller pad end includes a relatively softer material, and the second roller pad end includes a relatively harder material that forms a trimming edge for trimming off interfering material of an adjacent track shoe in a machine track that is plastically deformed by way of roller contact with the adjacent track shoe during service.
