Abstract
A seed meter assembly includes a motor, a seed reservoir, and a metering member having a seed side facing the seed reservoir and a non-seed side. The motor is configured to drive the metering member in a rotational direction moving from upstream towards downstream. The metering member includes a plurality of apertures for picking up seeds from the seed reservoir under the influence of a pressure differential. A cell diverges from an aperture of the plurality of apertures towards the seed side to define a surface recessed therefrom. The cell is configured to receive one of the seeds and is elongated between a first end defining a furthest extent of the cell in an upstream direction and a second end defining a furthest extent of the cell in a downstream direction. The aperture of the plurality of apertures is disposed closer to the second end than to the first end.
