Abstract
An agricultural planter includes a plurality of row units attached to a toolbar. The row units include seed meters in seed meter housings for receiving, singulating, and dispensing seed or other particulate. The seed meters include a circular seed disc with a seed path for receiving the seed in the seed meter housing. Integrated with the seed meter, such as at the housing, is an electric pressure source dedicated for providing a pressure differential for the seed meter or meters at a particular location on the planter. The pressure source can be positive or negative to temporarily adhere seed to the seed disc of the meter. A single pressure source can provide the pressure differential to a single meter or to multiple meters or discs at a row unit.
