Abstract
A row unit for a seeding machine includes a seed reservoir and a seed meter assembly having a metering member with a seed side facing the seed reservoir and a non-seed side opposite the seed side. The metering member is operable to selectively move seeds from the seed reservoir. A pump provides a pressure differential between the seed side and the non-seed side for adhering the seeds to the metering member. A conveyor has an inlet for receiving the seeds and an outlet configured to discharge the seeds from the seeding machine. The conveyor includes a belt movable from the inlet to the outlet. A pneumatic seed displacer includes a nozzle disposed adjacent the metering member for concentrating air. The nozzle is configured to eject the air towards the metering member for directing the seeds from the metering member to the conveyor.
