Spreader Parts

Concaves are a vital area of the threshing system that affects the entire operation of the combine. These parts do 100% of the threshing and up to 90% of the separation of the grain from its stem, cob or pod. Selection of the correct concave configuration is a key component to the performance of the combine in a wide variety of crops and conditions. Correct concave allows for increased threshing capability and maximum threshing performance.
