Track pad geometry for hard surfaces

Abstract:

A track chain member includes a first rib coupling the shoe member to the first lug; and a second rib coupling the shoe member to the second lug, defining a first side recess between the first rib and the second rib. The first side recess also extends from the exterior of the shoe member and underneath the first top surface, the first lateral end defines a first lateral end width along the track chain traveling direction, and the first side recess also spans the majority of the first lateral end width along the track chain traveling direction.
