Abstract
In a seed meter in which a seed disk having a circular outer edge is rotatably mounted on a hub within a generally cylindrical housing, an elongated cleanout and seed sealing member mounted within the housing adjacent a substantial portion of the circumference of the outer edge of the seed disk forms a generally uniform space or gap with the outer edge of the seed disk which is large enough to pass most seed chips, broken seeds, dirt and other debris therethrough but small enough to prevent seeds contained within the housing and adjacent the seed disk from escaping therethrough. The cleanout and seed sealing member has a sloped surface adjacent the outer edge of the seed disk which provides the space or gap with a size that increases with increasing distance from the axis of rotation of the seed disk to facilitate the escape of debris. The housing has a slot in the outer edge thereof adjacent the outer edge of the seed disk and the cleanout and seed sealing member which extends around a substantial portion of the circumference of the outer edge to facilitate elimination from the housing of debris which passes through the space or gap between the cleanout and seed sealing member and…
