Separating Process

Threshed straw and any remaining grain are deflected and thrown onto the straw walkers. The agitating straw walker action removes the remaining grain which falls onto the grain pan.

Avoid "underthreshing", whereby the straw walkers become overloaded and the separating action is too fast. As a result, grain passes over the straw walkers and out of the combine with the mass of the straw.

Check:
· Concave spacing narrow enough?
· Cylinder speed high enough?
