The track-type machine of claim 1 wherein the awning assembly is attached to the track roller frame and free from contact with the main frame. 3. The track-type machine of claim 2 wherein the track roller frame is movable a travel distance relative to the main frame in the inboard to outboard direction, the awning is spaced from the main frame a second distance which is greater than the travel distance, and the track chain is spaced from the main frame a third distance which is greater than the second distance. 4. The track-type machine of claim 3 wherein the track chain includes an oval track chain. 5. The track-type machine of claim 4 wherein the clearance between the track roller frame and the main frame includes a downwardly tapered funnel shape having a throat section and a stem section, and wherein the awning includes a plurality of segmental plates blocking an upper end of the throat section. 6. The track-type machine of claim 4 wherein the plurality of segmental plates includes a curved leading plate, a trailing plate, and at least one middle plate positioned between the leading and trailing plates, and wherein the awning assembly further includes a plurality of supports attached to the track roller frame, and also attached to at least one of the plurality of segmental plates. 7. The track-type machine of claim 2 wherein the track system further includes a carrier roller, and a carrier roller support mounted to the track roller frame, and wherein the awning assembly defines a cutout extending about the carrier roller support and having a shape complementary with a shape of the carrier roller support. 8. The track-type machine of claim 2 wherein the ground engaging track system further includes a second track roller frame, and a second awning assembly which is a mirror image of the first awning assembly and attached to the second track roller frame. 9. An undercarriage system for a track-type machine comprising: a track roller frame including a front end defining an idler pocket, a back end, an outboard side, and an inboard side, the track roller frame further including a front main frame connector positioned on the inboard side adjacent to the front end, and a back main frame connector, for coupling the track roller frame with a main frame of the track-type machine;a vertically upwardly projecting support for coupling with a track carrier roller, mounted to the track roller frame; anda debris shunting awning assembly mounted to the track roller frame and including an awning projecting from the inboard side, and a plurality of supports for the awning coupled with the track roller frame;the track roller frame including a frame length in a fore to aft direction between the front end and the back end, and the awning including an awning length in the fore to aft direction which is equal to at least a majority of the frame length, and an awning width in an inboard to outboard direction, such that the awning spans a majority of a clearance between the track roller frame and the main frame when the track roller frame is coupled with the main frame, and further having a downward slope toward the inboard side of the track roller frame for redirecting vertically falling debris horizontally through the undercarriage system. 10. The undercarriage system of claim 9 wherein the track roller frame further includes a box frame having a hollow interior open at the front end and in communication with the idler pocket, and the box frame defining a peaked upper surface profile in a section plane normal to the frame length. 11. The undercarriage system of claim 10 wherein the upper surface profile includes an inboard slope, an outboard slope, and a peak transitioning with each of the inboard and outboard slopes, and wherein the awning includes an awning slope which is steeper than the outboard slope relative to a vertical line within the section plane. 12. The track-type machine of claim 10 wherein a first subset of the plurality of supports is reversibly attached to the track roller frame, a second subset of the plurality of supports is irreversibly attached to the track roller frame, and the awning includes a plurality of segmental plates reversibly attached to the plurality of supports. 13. The undercarriage system of claim 12 wherein each of the plurality of segmental plates includes a different geometric footprint. 14. The undercarriage system of claim 13 wherein the plurality of segmental plates includes a total of four segmental plates. 15. The undercarriage system of claim 13 wherein the plurality of segmental plates includes a curved leading plate, a trailing plate, and a plurality of planar middle plates. 16. A debris shunting awning assembly, for an undercarriage in a ground engaging track system having a track chain and a track roller frame with a front end defining an idler pocket, and a back end, and where the track roller frame is configured to couple with a main frame by way of front and back main frame connectors positioned on an inboard side of the track roller frame, the debris shunting awning assembly comprising: an awning including a plurality of segmental plates including a leading plate, a trailing plate, and a middle plate, and each having a different geometric footprint and including inboard and outboard plate edges, and upper and lower plate surfaces, and having an assembly configuration at which the plurality of segmental plates are coupled with the inboard side of the track roller frame and together span a majority of a clearance between the track roller frame and the main frame in each of fore to aft and inboard to outboard directions; anda plurality of supports for the plurality of segmental plates, each of the plurality of supports being configured to attach to at least one of the segmental plates and to the inboard side of the track roller frame, in the assembly configuration, and including a front, a back, and a middle support, for the leading, trailing, and middle plates, respectively;the plurality of segmental plates together defining a uniform outer edge profile formed by the outboard plate edges, a non-uniform inner edge profile formed by the inboard plate edges, and a sloping upper surface profile relative to a plane defined by the middle plate, in the assembly configuration, whereby the debris shunting awning assembly directs debris through a middle segment of a debris path extending between an entrance segment defined at least in part by the main frame and the track chain and an exit segment defined at least in part by the track roller frame and the track chain. 17.
