1. A suspended undercarriage assembly connectable to a multi-member frame assembly of a track system, the multi-member frame assembly defining at least one recess, the suspended undercarriage assembly comprising:
a beam having a leading portion and a trailing portion, the beam further comprising a leading pin projecting from the leading portion of the beam and a trailing pin projecting from the trailing portion of the beam, wherein the leading pin and the trailing pin are integrally formed with the beam; the leading and the trailing pins defining a longitudinally extending undercarriage pivot axis;
at least one support wheel assembly connectable to the beam;
at least one of:
a leading resilient bushing assembly connected to the leading portion of the beam, wherein the leading resilient bushing assembly defines a leading aperture sized and dimensioned for receiving the leading pin for connecting the beam to the leading resilient bushing assembly; and
a trailing resilient bushing assembly connected to the trailing portion of the beam, wherein the trailing resilient bushing assembly defines a trailing aperture sized and dimensioned for receiving the trailing pin for connecting the beam to the trailing resilient bushing assembly;
wherein the at least one of the leading and trailing resilient bushing assemblies includes:
a rectangular housing; and
four bushings seated in the corners of the rectangular housing and being propped against the rectangular housing by the corresponding leading and trailing pins;
wherein the leading and trailing resilient bushing assemblies are deformable radially to allow pivoting of the leading and trailing pins about the longitudinally extending undercarriage axis.
