ABSTRACT:
An external shutoff element for a multiple row pneumatic seed planter having a transverse frame, a plurality of seed planting elements thereon, a hollow rotary seed selector drum with a plurality of spaced apart rows of seed retaining perforations which correspond to the planting elements, an airblower forcing air outwardly from within the drum thereby suspending individual seeds in a depression associated with each perforation so long as the perforation is not blocked, a discharge portion for dislodging the seeds from the perforations and delivering them to the respective planting elements, the improvement comprising a shutoff element movably mounted on the frame above the discharge portion for selectively engaging the outside of the drum to cover a group of rows of perforations so that the usual radial pneumatic bias generated by the airblower ceases to hold the seeds in the covered rows of perforations and they fall before the discharge portion can deliver them for planting. Electrical control and actuating elements including solenoids, switches and indicator lights are also connected to the shutoff elements to allow an operator in the cab of the tractor to selectively shut off rows of the planter.
