Abstract
A direct drive electric seed metering system is provided for use with a row crop planter or seed planter that intakes a volume of multiple seeds from a seed hopper, draws individual seeds from the volume of multiple seeds and discharges them into a seed furrow formed in an agricultural field. The direct drive electric seed metering system includes a meter assembly having a meter housing and a seed plate rotatably mounted concentrically in the housing for singulating the seeds. A direct drive mechanism is mounted to the meter assembly for interfacing and driving the seed plate at an angular velocity which corresponds to the travel velocity of the seed planter. A single seed planter can have multiple direct drive electric seed metering systems, and each of the multiple direct drive electric seed metering systems preferably has its own prime mover to effectuate driving the seed plate.
