Abstract
A track system for use with a towed vehicle has an attachment assembly and a multi-member frame assembly. The multi-member frame assembly includes a primary frame member connected to the attachment assembly, at least one wheel-bearing frame member pivotably connected to the primary frame member about a pivot located within a recess, and at least one resilient bushing assembly located within the recess and engaging the pivot. The at least one bushing assembly is resiliently deformable in a circumferential direction to permit pivoting of the pivot with respect to the recess, and is fixedly connected within the recess to resiliently bias the pivot towards a rest position with respect to the recess. The track system further includes leading and trailing idler wheel assemblies rotatably connected to the at least one wheel-bearing frame member, and an endless track.
