Abstract
Control apparatus for a pneumatic seed meter having a seed disc that uses a pneumatic pressure differential to hold and release seed on a rotating disc. The control apparatus is controlled to disrupt the pressure differential in an area of the rotating disc to selectively disrupt planting of seed by the seed meter to, for example, reduce overlap planting.
