FIELD: agriculture; engineering industry.
SUBSTANCE: agricultural planter includes a plurality of row units attached to a toolbar. Row units include seed meters for receiving, singulating, and dispensing seed or other particulate. Seed meters include a circular seed disc with a seed path for receiving the seed in the seed meter housing. Seed disc comprises a motor, having a substantially stationary inner member and a rotatable outer member, and a substantially circular member operatively attached to the motor such that rotation of the outer member rotates the circular member. Circular member, outer member and inner member are coaxial around the central axis of the seed disc to reduce the axial width of the seed disc and to increase the diameter of the motor. In the inner part of the circular seed disc, an integrated motor can be located in such a way that the combination of the width of the disc and the motor remains minimal.
EFFECT: use of the invention will reduce the axial width of the seed meter and simplify the replacement of the seed disc.
