Abstract
A wear liner for use with a brush cutter, the cutter having a cylindrical, rotatable, cutting drum carrying cutting teeth and a cover at least partially covering the drum to limit dispersal of cut material. The liner comprises a sheet of material which can be shaped to fit against the inner surface of the cover. The liner has holes on its sides for use in detachably connecting the liner with fastening means to the cover against the cover's inner surface. The liner has protective means mounted on its inner surface adjacent each hole to protect part of the fastening means located adjacent the inner surface of the liner, when the liner is mounted to the cover and the fastening means extend through the opening, from wear by material thrown by the cutter during its operation.The invention is also directed toward a brush cutter incorporating the liner.
