ABSTRACT:
A resilient element is associated with an overlapping portion of a crawler tractor track shoe so that the adjacent shoe initially contacts the resilient element during back-bend flexure prior to the grouser of this same adjacent shoe contacting the overlap portion of the first shoe. The resilient element, by reducing impact velocity, serves to lessen operating noise and prolong shoe life.
