Abstract
Official abstract text for this publication.
A metering device ( 24 ) for an agricultural planter ( 10 ) has a metering chamber ( 80 ) with a seed discharge ( 98 ) area and a metering disc ( 66 ) rotatable within the metering chamber ( 80 ). The metering disc ( 66 ) has plurality of seed pockets ( 68 ) for carrying seeds on the metering disc ( 66 ), the seed pockets ( 68 ) being disposed at mutually spaced locations about the metering disc ( 66 ). The metering disc also has a magnetic drive ring ( 136 ) in the outer periphery of the metering disc ( 66 ). The metering device also has a stator positioned adjacent the metering disc. The stator ( 132 ) interacts with the magnetic drive ring ( 136 ) to rotate the metering disc ( 66 ) within the metering chamber ( 80 ) such that the seed pockets ( 68 ) move successively in proximity to the discharge area ( 98 ) during rotation of the metering disc ( 66 ).
