ABSTRACT:
A mechanical seed meter having a stationary housing and a rotatable bowl. The stationary housing is provided with an axial inner wall, a radial outer wall and a flexible radial inner wall. The bowl is provided with seed receiving cells that form an axial outer wall for trapping singled seeds in the seed trapping area. A flexible and resilient insert together with an axially extending brush removes excess seeds from the seed receiving cells as they pass through the seed puddle before entering the seed trapping area. The seed slides along the radial outer wall by centrifugal force until it enters the outlet area from which the radial outer wall becomes part of the outlet and the metered seed is deposited through the outlet to a seed tube.
