Abstract
A seed meter disk includes a body defining a plane of rotation, a seed-side, and a lower-pressure-side. A circumferential array of seed openings are provided on the seed-side of the seed meter disk for seed adherence. A circumferential array of kick-out pockets are provided on the lower-pressure-side of the seed meter disk. A circumferential array of recessed seed agitator pockets may be provided for seed mixing and agitation. A circumferential array of raised agitator pegs or features may be provided for seed mixing and agitation. A kick-out wheel assembly includes a kick-out wheel rotatably held by a kick-out wheel arm. The kick-out wheel has at least one protrusion portion including a plurality of kick-out protrusions each of which is configured to mate with and enter one of the kick-out pockets to facilitate dislodgement of a seed or other particle from within a seed opening.
