FIELD: agriculture.

SUBSTANCE: pneumatic planting attachment contains body, seed disk with openings, vacuum chamber, kickoff of excess seeds and agitator. Agitator allows additional blades. Active faces of additional blades are directed in the line of rotation of agitator and to the plane of seed disk. Additional blades allow equal length, its number is multiple of three, and shapes of active faces of additional blades are different and change cyclic. Additionally in each cycle of shape of additional blades there are sequentially implemented in the form of concave, flat and convex surface.
