Abstract
A seeding machine is provided with a frame having a plurality of pneumatic seed meters. An air pump located on the frame supplies air pressure to a pneumatic manifold. The pneumatic manifold in turn is pneumatically coupled to the seed meters by air hoses. Pneumatic orifices are pneumatically positioned between the pneumatic manifold and the portion of the seed meters closest to the air pump.
