Abstract:
A seed meter is provided for use with a row crop planter or seed planter that includes a seed disk assembly that rotates within a meter housing cavity and that has a seed disk assembly cavity in which a vacuum pressure is applied for pulling seeds into seed pockets of a seed disk of the seed disc assembly. The vacuum pressure is applied to the seed disk assembly by pulling a vacuum airflow through a spindle that supports the seed disk assembly. A wiper basket is arranged in a fixed position within the seed disk assembly cavity and seals against the seed disk assembly as a support plate and seed disk of the seed disk assembly rotate over the wiper basket, so that side walls of the wiper basket create a boundary between a vacuum zone and a non-vacuum zone inside of the seed disc assembly cavity.
