ABSTRACT:
A mobile planter of the pneumatic type which has a rotating drum with seed receiving apertures arranged so that seed is deposited at an upper peripheral surface of the drum to be received in the seed receiving apertures. The exterior of the drum is maintained at a higher pressure than the interior of the drum so that the resultant pressure differential holds seeds in the apertures until they are released from the drum at the lowest point in the path of travel of the drum surface from which the seeds are conveyed by tubes utilizing the pressure at the exterior of the drum for deposit in the ground.
