  • Seed sower having apertured pick-up member
    Patent number: 4239126
    Abstract: A seed sower is provided having an apertured driven pick-up member which has spaced apertures in its periphery in communication with a suction member. The apertures are moved through seed storage means so that single seeds are picked up by the pick-up member by suction and held over each aperture. The seeds are carried to a discharge locality and released for planting. The pick-up member is hollow and has an internal sealing member which contacts each spaced aperture adjacent to the discharge locality thereby sealing off the suction and allowing each seed to travel to the discharge locality.
