A ground engaging track for a track-type machine includes a set of identical standard track shoes each having a relatively narrow shoe footprint, and a sweeping track shoe having a relatively wide shoe footprint. The sweeping track shoe is connectable via track links with the standard track shoes in an endless chain configuration such that the sweeping track shoe juts outwardly of the standard track shoes, for sweeping debris from a clearance between the track and a main frame of the track-type machine. The sweeping track shoe includes bolting apertures formed therein and communicating between an upper shoe surface and a ground contacting shoe surface, the bolting apertures 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 may be configured such that an inboard sweeping edge is spaced further than an outboard edge from the minor shoe axis.

1. A ground engaging track having track shoes with inboard and outboard edges connectable via track links in an endless chain configuration about a drive sprocket and an idler in a track-type machine, the ground engaging track comprising: a set of identical standard track shoes each including a standard shoe body having bolting apertures formed therein and communicating between an upper shoe surface and a ground contacting shoe surface, and an outer perimeter defining a first shoe footprint;a sweeping track shoe, for sweeping debris from a clearance between the track and a main frame of the track-type machine, including a sweeping shoe body having bolting apertures formed therein and communicating between an upper shoe surface and a ground contacting shoe surface, and an outer perimeter defining a second shoe footprint which is wider than the first shoe footprint;a ground contacting footprint of the track being a composite of the first and second shoe footprints of the standard and sweeping track shoes;the bolting apertures in each of the standard track shoes and the sweeping track shoe being arranged in an identical link bolting pattern, such that the sweeping track shoe juts in an inboard direction outwardly of the standard track shoes in the endless chain configuration, and the ground contacting footprint juts in coincidence with the sweeping track shoe. 2. The track of claim 1 wherein each of the standard shoe bodies and the sweeping shoe body includes a one-piece shoe body have upwardly curved leading edges, downwardly curved trailing edges, and a grouser extending between inboard and outboard edges and including a portion of the corresponding ground contacting shoe surface. 3. The track of claim 2 wherein the link bolting pattern includes a directional pattern defining a minor shoe axis intersecting the leading and trailing edges and a major shoe axis oriented normal to the minor shoe axis and intersecting the inboard and outboard edges, of the corresponding track shoe. 4. The track of claim 3 wherein the standard shoe minor axes are spaced a first distance from the corresponding standard shoe inboard edge, and the sweeping shoe minor axis is spaced a second distance from the sweeping shoe inboard edge. 5. The track of claim 4 wherein the second distance is greater than the first distance. 6. The track of claim 5 wherein the sweeping shoe body includes a standard outboard profile, and an anti-snagging inboard profile. 7. The track of claim 6 wherein the standard shoes and the sweeping shoe are in the endless chain configuration and define an oval track shape about the drive sprocket and the idler of the track-type machine. 8. The track of claim 7 further comprising a second sweeping shoe positioned in the track opposite the first sweeping shoe. 9. An undercarriage system for a track-type machine comprising: a track roller frame including an elongate body having a front end and a back end;an idler coupled with the front end of the track roller frame;a drive sprocket; anda track chain extending about the drive sprocket and the idler, the track chain including inboard and outboard track chain edges, and having a set of identical standard track shoes each including an outer perimeter defining a first shoe footprint; andthe track chain further having a sweeping track shoe including an outer perimeter defining a second shoe footprint which is wider than the first shoe footprint;the track chain further having a ground contacting footprint which is a composite of the first and second shoe footprints of the standard and sweeping track shoes, and the sweeping track shoe being coupled with the standard track shoes, such that the sweeping shoe juts outwardly of the standard track shoes in an inboard direction, for sweeping debris from a clearance between the track chain and a main frame of the track-type machine, and the ground contacting footprint juts in coincidence with the sweeping track shoe. 10. The undercarriage system of claim 9 wherein the elongate body includes a box frame having a hollow interior, and defining a longitudinal axis extending between the front and back ends, and the box frame further including an upper surface having a peaked upper surface profile in a section plane normal to the frame length. 11. The undercarriage system of claim 10 wherein the peaked upper surface profile includes a relatively steeper inboard slope, a relatively shallower outboard slope, and a peak transitioning with each of the inboard and outboard slopes. 12. The undercarriage system of claim 10 wherein the track chain includes an oval track chain having a uniform outboard chain edge and a non-uniform inboard chain edge, and wherein the sweeping track shoe includes an inboard sweeping edge comprising a segment of the non-uniform inboard chain edge. 13. The undercarriage system of claim 12 wherein each of the standard track shoes and the sweeping track shoe includes an upper shoe surface, a ground contacting shoe surface, and a set of bolting apertures communicating between the respective upper and ground contacting shoe surfaces, and wherein the sets of bolting apertures are arranged in identical link bolting patterns. 14. The undercarriage system of claim 13 wherein each of the sets of bolting apertures is arranged in a directional pattern and defines a minor shoe axis, and a major shoe axis, and wherein each of the standard track shoes is symmetric about the corresponding minor shoe axis, and the sweeping track shoe is asymmetric about the corresponding minor shoe axis. 15. The undercarriage system of claim 10 wherein each of the standard track shoes and the sweeping track shoe includes an upwardly curved leading edge, a downwardly curved trailing edge, and inboard and outboard shoe edges extending between the corresponding leading and trailing edges, and wherein each of the standard track shoes and the sweeping track shoe further includes a grouser extending between the corresponding inboard and outboard edges. 16. The undercarriage system of claim 15 wherein the sweeping shoe includes a standard outboard profile, and an anti-snagging inboard profile. 17. A track-type machine comprising: a main frame;an undercarriage system coupled with the main frame and positioned at a clearance therewith, the undercarriage system including a track roller frame, an idler mounted to the track roller frame, a drive sprocket, and a ground engaging track chain extending about the idler and the drive sprocket;the ground engaging track chain including a set of identical standard track shoes each defining a standard shoe footprint, and a sweeping track shoe defining a nonstandard shoe footprint and jutting from the standard track shoes toward the main frame, for sweeping debris from the clearance; andthe standard shoe footprint and the non-standard shoe footprints together forming a ground contacting footprint of the track chain jutting coincident with the sweeping track shoe. 18. The track-type machine of claim 17 wherein each of the standard track shoes includes a one-piece standard shoe body, and the sweeping track shoe includes a one-piece sweeping shoe body, and wherein the standard shoe footprint includes a relatively narrow footprint and the nonstandard shoe footprint includes a relatively wide footprint. 19.
