Bolting of the anchor plate on a track shoe normally provides exposed bonded edges that are subjected to high tensile stresses or failure during tractor operation. In addition, soil and the like tends to ingress into the bonded edges to further induce bond failure. The grouser assembly (11) of this invention overcomes these problems by providing a compressed lip portion (27) of an elastomeric grouser (12) between a rib (24) formed integrally on the track shoe and each outer side (28) of an anchor plate (13). In addition, a static seal (30) is formed between the lip portion (27) of the grouser (12) and the rib (24). | |
