Abstract
The soft bottom track assembly of the present invention includes inner pad assemblies, side plate assemblies, and link and cross bolt assemblies. An inner pad assembly includes a multiplicity of longitudinally arranged pads, hingedly attached one to the next, each having an upper iron casting with a rubber/urethane material bonded thereto. The pads are arranged in rows, with each row staggered from each adjacent row so that there are always pads in contact with the surface on which the track is riding. A raised area on the cast iron backing provides traction between the tire and the track assembly. Each pad includes holes for hinged attachment to adjacent pads, also permitting adjustment of the size of the track length, depending on the hole arrangement selected during track assembly installation.
