Abstract
A concave for an agricultural combine having an array of straight rectangular bars and straight round bars spaced from one another and extending axially of the rotor or cylinder to form a threshing surface and to form openings therebetween for grain to pass through. The round bars shed crop material to reduce plugging while the rectangular bars provide an aggressive threshing edge. Smaller diameter wires can be inserted between the round and rectangular bars to reduce the opening size for use with small grains.
