This section provides information on commonly replaced wear parts for combines. Guidelines are given on how to determine when these parts are worn and should be replaced.
The importance of replacing worn components on a combine cannot be overemphasized. Worn components result in poor combine performance, reducing profits. For example, up to 80 percent of crop loss can occur at the platform or header area of the combine. Whether you’re harvesting wheat, barley, rice, soybeans, corn, grain-sorghum, or other crops, proper cutterbar or gatherer unit maintenance and regular replacement of worn parts will reduce loss and increase profits.
Feeding, threshing, and separating performance is reduced if maintenance and replacement of worn parts are not done at the proper time. Poor feeding of material to the threshing area can cause plugging, which can result in cylinder drive component failure or incomplete threshing.
Worn threshing components cause incomplete threshing or grain damage when cylinder speed is increased to compensate for worn components. Worn material-handling components, such as augers and elevator paddles, can result in reduced combine productivity.
