Abstract
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).
