ABSTRACT:
A tracked machine may be equipped with a debris guard in order to inhibit entry of debris from an exterior to an interior of a track roller frame. An idler, track roller frame, track and debris guard may be configured to create a difficult to traverse serpentine debris entry pathway into the track roller frame. This may be accomplished by flanking opposite sides of a track chain with a pair of guard plates, and further inhibiting debris entry by including an in board guard shield that defines a slot that surrounds a portion of the idler.
