Abstract: A particulate delivery system for use with a mobile machine includes a particulate placement mechanism for placing particulate material in the ground in a single row as the machine travels along the ground, a plurality of particulate sources and a plurality of particulate meters. Each of the particulate meters operates independently and is configured to deliver particulate material from one of the particulate sources to the particulate placement mechanism for placement in the row. A controller may be configured to control a plurality of drive mechanisms, each drive mechanism associated with one of the particulate meters. The controller may also be configured to receive position information from a position determining device and to control operation of the drive mechanisms according to the position information and according to a field prescription.

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).
