ABSTRACT:
A wear shield is attached to a cutter bar and is formed from a molded wear body having a front mounting portion bolted onto the guards of the cutter bar by the guard mounting bolts with recesses for the guard fingers and a front edge of an upper planar mounting surface clamped onto the guard bar. A rear covering portion is cantilevered rearwardly from the front mounting portion underlying a bottom plate of the cutter bar for engaging the ground so as to underlie and protect the bottom plate. Resilience in the wear shield forces the rear part against the bottom plate of the cutter bar to avoid the necessity for a rear fastener. A series of the wear shields is arranged side by side across the cutter bar with two side edges each for locating adjacent a side edge of a next adjacent wear shield.
