An analysis of the works devoted to the theory of the working process of sowing seeds of grain crops shows that the sowing machines are one of the most important working parts of the seeder, which, during their work, must ensure not only a continuous and uniform flow of seeds, but also the necessary stability of the established seeding rate, as well as the possibility of sowing seeds of various crops, the minimum injury of seed. The article is devoted to improving the quality indicators of sowing seeds with seeders for sowing grain crops using environmentally friendly technologies equipped with new coil-screw sowing machines with coils, the grooves of which are turned along a helix at an angle of 20 degrees, as well as a sowing machine with an increased volume of coil grooves, obtained correlations and graphic dependencies between the uneven distribution of seeds along the length of the row, on the forward speed of the sowing units equipped with seeders with the studied sowing machines.
