In a track-type vehicle, a high wear-resistant insert is bonded into a groove in the contact face of a grouser bar of a track shoe so as to extend the useful life of the grouser. The grouser bar may be integrally formed on the track shoe or may be a separate part welded to a base plate to form a composite track shoe. The material of the grouser bar may be somewhat ductile so as to support the relatively hard and brittle wear-resistant insert in the contact face of the grouser so as to produce a long life track shoe.

Wear-resistant composite track shoe

A track-type vehicle having a track made up of links with contact surfaces of high wear-resistant material engaging with the track rollers as the track is driven on the vehicle. The high wear-resistant material may be a composite alloy metallurgically bonded into a groove in the contact surface.
