Abstract
An air seed meter for an agricultural planter includes a vacuum cover which has a central opening which exposes the central portion of the seed disc to the exterior. The central opening of the vacuum cover is centered on a location offset from the axis of rotation of the seed disc. This reduces disc wear at the disc-vacuum cover interface, and renders the disc more accessible for self-cleaning, visual inspection and verification of the proper disc. Openings in the central, open portion of the disc, the back wall of the seed housing and the side wall of the seed housing cooperate to equalize the air pressure in the seed reservoir to atmospheric pressure and reduce or eliminate reverse air currents in the discharge chute. An adjustable brush with three separate stations cooperates with an edge-release, beveled disc to apply a progressively more forceful singulation force to eliminate duplicate seeds.
