    Abstract: A ground engaging track (12) for a track-type machine (8) includes a set of identical standard track shoes (26) each having a relatively narrow shoe footprint, and a sweeping track shoe (28) having a relatively wide shoe footprint. The sweeping track shoe (28) is connectable via track links (38) with the standard track shoes (26) in an endless chain configuration such that the sweeping track shoe (28) juts outwardly of the standard track shoes (26), for sweeping debris from a clearance between the track (12) and a main frame (10) of the track-type machine (8). The sweeping track shoe (28) includes bolting apertures (42a, 42b) formed therein and communicating between an upper shoe surface (44) and a ground contacting shoe surface (46), the bolting apertures (42a, 42b) being arranged in a directional link bolting pattern. The directional link bolting pattern defines a minor shoe axis and a major shoe axis, and the sweeping shoe body (40) may be configured such that an inboard sweeping edge (52) is spaced further than an outboard edge (50) from the minor shoe axis.
