The new BLS Poly Bolt-On track pad is a two-piece assembly consisting of a conventional, triple-grouser, steel track shoe and a bolt-on polyurethane pad. The basic advantage of the design, says BLS, is that the pads can be replaced without disturbing the grouser. Pad mounting bolts are positioned to the outside of the grouser to reduce the prospect of torch heat (when burning off the mounting nuts) from harming lubricated chains. Other benefits, says BLS, include less replacement labor (since the metal grousers stay in place), lower replacement costs (since only the pad need be replaced), and reduced shipping costs.
