First Claim
Patent Images
1. A seed disc, comprising:
- a motor including 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;
wherein the circular member, outer member, and inner member are at least partially coaxial to reduce the axial width of the seed disc.

Abstract
An agricultural planter includes a plurality of row units attached to a toolbar. The row units include seed meters 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 disc is a motor that is housed within the seed meter housing and that includes a rotatable portion being attached to the circular disc such that the two rotate in tandem. The integrated motor can be positioned within an interior portion of the circular seed disc such that the width of the disc and motor combination is kept to a minimum.
