ABSTRACT:
A seed singulator uses two opposing surfaces, one of which has a groove extending across it dimensioned to receive seeds in a single file. The two surfaces are moved relative to each other, with the groove having an angled relationship of less than 90.degree. with the relative direction motion of the two surfaces. Variation of the angle controls spacing between seeds independently of the velocity of relative movement between the surfaces. The surfaces are preferably flat with a centrally disposed seed containing area and the groove extending from that area to the periphery of the surfaces for discharge of the seed. In this form, the relative motion between the surfaces is preferably rotary to provide continuous operation.
