Abstract: A ground working implement formed from a hard substrate material such as steel has a forward facing ground cutting edge. A wear resistant coating (59, 63) such as polyurethane is applied to at least one face of the implement. The coating adjacent the cutting edge may have a cut (66), trench or line of weakness formed in it substantially parallel to the cutting edge. The implement may be a cultivator tillage point having a generally triangular shaped working portion with a nose (56) and a pair of wings swept back therefrom, with the leading edge of the nose and wings forming a cutting edge. The metal at the rear of the nose portion is stepped (58) in order to protect the leading edge of the plastics material immediately behind the nose.
