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; a leading pin projecting from the leading portion and a trailing pin projecting from the trailing portion;
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, the leading resilient bushing assembly defining 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, the trailing resilient bushing assembly defining a trailing aperture sized and dimensioned for receiving the trailing pin for connecting the beam to the trailing resilient bushing assembly; and
the at least one of the leading and trailing resilient bushing assemblies being at least partially receivable in the at least one recess for connecting the beam to the multi-member frame assembly, the at least one of the leading and trailing resilient bushing assemblies including a bushing having an opening defined therein and being shaped and dimensioned for promoting deformation of the bushing in at least one of a vertical direction and a lateral direction, the bushing being resiliently deformable to permit movement of the beam relative to the multi-member frame assembly in the vertical direction and in the lateral direction, and to resiliently bias the beam towards a rest position with respect to the multi member frame assembly.
