Abstract: The seed cleaner comprises a scalper drum which drives an auger pick up and which separates all materials thicker than the desired seed such as head, stalks and the like. The remaining fraction then passes through an air cleaner which removes chaff, dust and light fractions. The remainder is fed into a pair of shells or drums which screen out seed and the like which is thinner than the desired fraction and then this desired fraction passes into an indent or pocket-type separator drum. This indent drum includes two sections, the first section which removes seeds shorter than the desired length and the second section which removes and discharges longer than desired seeds. The remaining seed is fed from the second section and collected at the discharge end of a trough pick up of the indent drum.
