    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 to create 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.

    Abstract: A seed metering system, for use on a row crop planter, selects individual seeds from a seed reservoir and dispenses the seeds singularly at a controlled rate. A direct drive seed metering system includes a seed disc having a plurality of suction apertures with a recessed pocket adjacent to an aperture. The recessed pockets act to agitate seeds in the seed reservoir and to direct seed flow towards the apertures. A seed path relief system aids in the placement of the seeds such that they are released from an outer edge of the seed disc. An adjustable seed singulator is mounted adjacent to the face of the seed disc where inner and outer blades are adjusted radially to compensate for the singulation of various seed sizes and shapes. The seed disc is driven via engagement of an internal gear with the external gear of an independent drive motor.
