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 band provided to accomodate the heads of track shoe retaining bolts underlying the grouser, the band 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 bead (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 band interface across the mounting plate (32). |
