There’s nothing more important to us than keeping you up and running, especially during critical harvest times. The harvest season puts huge demands on your equipment and unexpected breakdowns or poor performance cost money. With the season ahead, now is the time to give your harvester a full service so it’s ready to go at a moment’s notice. To harvest to your crop’s full potential you need the support of the John Deere dealership network committed to keeping your harvester operating at its full potential.

This section provides information on commonly replaced wear parts for combine harvesters. 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 harvester cannot be overemphasised. 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.
