Abstract
A seed meter includes a meter housing having a first chamber for seeds and a second chamber. A seed disk is rotatably supported within the meter housing and has a first side and a second side. The first side is exposed to the first chamber and the second side is exposed to the second chamber. The seed disk includes a plurality of seed openings that extend between the first and second sides at a predetermined radial position. A singulator is positioned against the first side of the seed disk and has at least one structure for removing excess seeds from the seed openings as the seed meter disk rotates relative to the singulator. A radial position of the singulator is controlled at least in part by a hub portion of the seed meter. A biasing spring is positioned to exert an axially-oriented bias force pressing the singulator against the first side of the seed meter disk.
