Roadable grouser for track shoes

Abstract

A roadable track shoe grouser is provided for track-type vehicles, for example, tracked farm tractors, to prevent damage to finished road surfaces when driving such tractors upon such road surfaces. The grouser includes a rubber grouser bar which is bonded to a mounting plate to facilitate replacement of the grouser after the rubber grouser bar is worn out by use. Owing to interruptions in the bond provided to accommodate the heads of track shoe retaining bolts underlying the grouser, the bond is subject to premature failure, resulting in the loss of the rubber grouser bar from the track shoe. The grouser 10 described herein solves this problem by using a mounting plate 32 having an aperture 45, the aperture 45 is of a size to receive a head 28 of a track shoe retaining bolt 25. A plug 50 is of a size and construction to be press fitted into and close the aperture 45 and to provide a continuous, uninterrupted bond interface across the mounting plate 32.
