Abstract
A planting unit for a seeding machine is disclosed having a frame member and a seed meter mounted thereto. The seed meter has a housing and a metering member rotatably mounted therein. The metering member has a sidewall with an inner surface and an outer surface and a rim portion adjacent an outer edge of the sidewall. The inner surface of the side wall and the housing form a trough at a bottom portion of the metering member to hold a seed pool. A mechanical seed delivery system takes seed from the metering member and moves seed to a discharge location adjacent a seed furrow formed in soil beneath the seeding machine.
