Abstract: In the operation of a construction machine over terrain strewn with debris, there is a tendency for the debris to work itself into areas of sealing interface such as between an axle and the final drive assemblies of the machine. When this occurs the seals and possible the life of the drive components can be greatly reduced. The present invention comprehends a guard assembly that has a bracket member that is positioned on an axle adjacent a cylindrical hub defined by the wheels. The guard assembly utilizes a plurality of plates positioned within, above and laterally spaced from the hub of an adjacent wheel to prevent the ingress of foreign material into the hub. The hub and the sealed interfaces and other components housed therein are thereby protected from possible damage as a result of contact with the foreign material.
