Abstract
The sprocket member keeps the sprocket centered within the link box while the notches or cut-outs allow mud, dirt, or other material to move out of the link box formed of the track chain assembly by two track bushings and two track links that form a rectangular shaped perimeter. The spacing provided by the wings of the sprocket member reduce wear on the track links near a track bushing and track link interface such as a press-fit connection by spacing the lugs of the sprocket member away from the interface.
