The analysis of various methods of sowing of grain crops showed that the introduction of indirect sowing in agricultural production contributes to the increase in their productivity. The authors propose justified structural and technological scheme of the sowing system in order to ensure a uniform distribution of seeds over the feeding area to a given depth with their subsequent seeding. The main element of the sowing system is the pneumatic seed feed. Due to the movement in the airflow, the seeds of grain crops at the moment of the concussion against the surface of the distributor have sufficient speed to reach any point on the surface under a V-shaped weep; this contributes to the uniform distribution of seeds across the entire width of the sowing strip.
