Patent abstract
A chemical granule metering system, for use on a row crop planter, allows for control of chemical granule drop rate. The chemical granule metering system also includes a motor permitting control of chemical granule drop rate by adjusting the rotational speed of the motor. An impeller for a chemical granule meter system having a plurality of apertures is optimized to allow a broad range of chemical granule flow rates, reduce or mitigate clogging, and reduce pulsing characteristics of the metering system.
