Abstract
A pneumatic seed meter comprises a housing and a rotatable seed disc. The rotatable seed disc divides the housing into a reduced air pressure side and a seed side. The rotatable seed disc is provided with seed cells to which individual seeds are attracted by an air pressure. A double eliminator is located in the housing on the seed side so that the double eliminator knocks extraneous seeds from the seed cells of the seed disc. The double eliminator is provided with an adjustment knob extending outside the seed side of the housing for adjusting the position of the double eliminator relative to the seed disc. A transparent viewing window is mounted on the seed side of the housing opposite the double eliminator so that adjustment of the double eliminator can be monitored.
