Abstract
A seed meter disk includes a body defining a plane of rotation. A circumferential array of seed openings are provided for seed adherence. A circumferential array of seed agitator pockets are formed as depressions in the first side of the body, each one of the array of seed agitator pockets having a radially inner end, a radially outer end, and a trailing edge extending from the radially inner end to the radially outer end. At least a portion of the trailing edge of one or more of the seed agitator pockets is backswept so that a circumferential-direction offset from a radial reference line rotationally ahead of the trailing edge, with respect to rotation of the seed meter disk in an operational direction, increases toward the radially outer end. The backswept portion is non-linear.
