A rotating concave grain threshing system (24) has a rotor assembly (26) positioned within a concave assembly (28). The rotor assembly (26) and concave assembly (28) are independently connected to a power source (36) and each are rotatable in a preselected direction at different rotations speeds through respective transmissions (38, 62) connected between the power source (36) and the rotor assembly (26) and concave assembly (28). |
