摘要：
A row unit for a seeding machine includes a seed reservoir and a seed meterhaving ametering member configured to rotate about an axis. The metering member has aseed sidefacing the seed reservoir, a non-seed side opposite the seed side, and aplurality of apertures.The axis is normal to a surface of the seed side. The seed meter is operableby pressuredifferential between the non-seed side and the seed side to adhere seeds tothe seed side andmove seeds from the seed reservoir. The row unit also includes a positivepressure air sourceand an air outlet fluidly coupled to the positive pressure air source. The airoutlet is disposedon the seed side and aimed to discharge an air stream towards one aperture ofthe plurality ofapertures. The dischargeable air stream has a directional component parallelto the axis.
