Abstract: A seed selector comprising a vertical cylinder blocked at both its upper and lower ends with a central opening on its lower end which flares outwardly in the downward direction. A piston in the cylinder has secured to its lower end three spring wire fingers that extend out through the central opening and spread apart therebelow, each finger having an inwardly hooked end. When fluid pressure is applied, typically as a vacuum to the upper end of the piston, the piston is raised upwardly and the fingers are moved upwardly while the hooked ends move inwardly so that they can seize between them a seed and lift the seed. Generally speaking, the device is then moved to another position and the seed is dropped by bleeding the vacuum to atmosphere so that the piston drops to its lowest position and the fingers open.
