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.
Claims20
A skid shoe for use on a skid plate of an agricultural crop combine header comprising:
- a one-piece member of ultra high molecular weight polyethylene plastic having a generally flat rear section and an upwardly inclined front section, said rear section having a thickness of at least twice the thickness of the front section, said member progressively and uniformly increasing in thickness from the front section to the rear section thereof, said member being made by a molding process which subjects powder plastic to heat and pressure to cause the powder plastic to become a coherent mass having the shape of the skid shoe.
A skid shoe for use on a skid plate of an agricultural crop combine header comprising:
- a one-piece plastic member having a front section and a rear section, said rear section having a thickness substantially greater than the thickness of the front section, said member increasing in thickness from the front section to the rear section thereof, said member being made by a molding process which subjects powder plastic to heat and pressure to cause the powder plastic to become a coherent mass having the shape of the skid shoe.
A skid shoe for use on a skid plate of an agricultural crop combine header comprising:
- a one-piece member of low friction material having a front section and a rear section, said rear section having a thickness substantially greater than the thickness of the front section, said member increasing in thickness from the front section to the rear section thereof.
