ABSTRACT OF THE DISCLOSURE An elongated, inclined sieve frame is provided and the frame includes a plurality of elongated transversely extending and transversely corrugated sheet metal sections arranged in laterally spaced parallel relation in an inclined plane extending lengthwise of the sieve frame. Each sheet metal section is substantially transversely straight throughout its transverse extent and corresponding portions of the corrugations of adjacent sections are disposed in parallel planes oppositely inclined relative to the inclination of the first-mentioned plane. The sieve frame is suspended at its opposite ends through the utilization of elastic suspension members and stricture is provided and operatively connected to the longitudinal mid-portion of the frame to impart omnidirectional vibration thereto in a vertical plane normal to the first-mentioned plane and the aforementioned parallel planes. Further, structure is provided for supplying the upper portion of the sieve frame and the corrugated sheet metal sections supported therefrom with a generally constant rate supply of grass seed supporting grass stalks.
