Abstract
A shearbar comprises an elongated mild steel body having a top surface covered with a layer of hardfacing material along at least one longitudinal edge to act as a counter knife to a rotary cutter. To resist the development of a wear gully on the vertical side of the body below the cutting edge of the hardfacing material the body has a region having a hardness intermediate that of the steel body and the hardfacing layer, extending along and immediately below the longitudinal edge of the hardfacing layer. In one embodiment the region is an inlay of tool steel. In another embodiment the region is formed by heat-hardening the corners of the body itself.
