Abstract
A rotary combine is equipped with a rotor that has a separating portion having at least one ramp segment mounted to the rotor. The ramp segments provide an inclined face that directs the grain radially outward as the ramp segments move through the crop material. The ramp segments are intermixed with tines on the separator section of the rotor. The ramp segments provide a face that is trapezoidal in shape, having inwardly inclined front and rear edges so that the radially distal edge of the face is shorter than the proximal edge of the face. The trapezoidal shape of the ramp segments assists the ramp segments in shedding crop material and thereby preventing the crop material from becoming entangled thereon.
