A pneumatic sowing unit comprises a body, on the driving shaft of which a sowing disk and an agitator are arranged. Between the sowing disk and agitator an additional disk, which has figure cuts along the contour, is arranged. The diameter of the additional disk is larger than the middle diameter of a seed by 1.1-1.2 times, and, to raise the probability of falling the seeds into the cuts and lowering traumatizing thereof, the front edge of the additional disk has a chamfer. |
