With increasing supply of seed of grain crops on the deflection surface of the seed distributor, which has the shape of a horizontal surface, the irregularity of seed distribution in the distributing head of the pneumatic seeder increases. This is due to the fact that the number of crop seeds that do not reach the deflector increases due to the seeds flying ahead, because as they fly away they reduce their speed and prevent them from moving easily to the deflector. As a result, the seeds collide with each other and are dispersed in a different pattern than the seeds that are deflected by the deflector, resulting in a much smaller dispersal area. A change in seed distri-bution occurs: the seed tubes in the center of the seed distributor receive slightly more seeds than those at the edges of the distributor, increasing the irregularity of seed distribution. This problem complicates the develop-ment of distributors shaped like a horizontal surface for pneumatic grain seeders with a sowing width of more than five meters, because in this case the first distribution stage receives a much higher load and the above-mentioned disadvantage of seed distribution occurs. This disadvantage can be eliminated by distributing the seeds over the deflector plate of the distributor. This requires the installation of an additional deflecting plate in the seed distributor [6, 9].
