ABSTRACT:
An agricultural crop combine has a header with skid plates and low friction plastic skid shoes mounted on the skid plates. Each skid shoe has a thickness that progressively and uniformly increases from the front end to the rear end of the shoe. The skid plates are made with a sinter molding process that subjects powder plastic in a mold to heat and pressure to cause the plastic to become a coherent mass comprising the complete skid shoe.
