ABSTRACT:
A selector device for a distributor of a so-called "single-seed" seed drill. It comprises a transportation member, a surface of which moves continuously between a seed hopper and a transportation device with, in that surface, orifices communicating with a vacuum source for maintaining by suction the seeds against that surface. A groove formed on the distributor surface extends over the suction orifice, the axis of the groove being perpendicular to the path of travel of the suction orifice, with a deflector the limit of the action range of which is clear from the path of travel of the axis of the suction orifices by about the radius of a seed.
