Load absorbing means for cutting edge assembly

摘要

A specialized load absorbing apparatus is disclosed for fastening tooth adaptors adjacent the cutting edge of an earthworking tool. The adaptor is especially useful with relatively sharp cutting edges wherein the edge itself cannot be used to absorb the load. The apparatus includes conical seats between the adaptor and the cutting edge and/or a specialized wear plate which locates below the cutting edge and absorbs some of the forces exerted on the adaptor.
