One of the main and most significant working bodies of a grain seeder remains the seeding unit due to the fact that the quality indicators of sowing depend on its work (unsatisfactory spread of seeds per unit length or seeding space, inaccuracy of the established seeding rate, as well as seed crushing). Not all seeding units comply with the necessary requirements during the operation, therefore, scientists of the Penza State Agrarian University have designed, manufactured and studied the seeding unit of a grain seeder with inclination of ridges, grooves and partitions of the grooves of a fluted roller. During laboratory and field studies of the seeding unit of an ordinary seeder with inclination of ridges and grooves and partitions of the grooves of a fluted roller, the spreading of seeds per unit length of spring wheat of the Bezenchukskaya 200 variety, the inaccuracy of the established seeding rate and the crushing of the seed material depending on the translational speed of the ordinary seeder were investigated. In the course of laboratory and field studies of the seeding unit of a grain seeder with inclination of ridges and grooves and partitions of the grooves of a fluted roller, it was found that the interval of the values of speed of an ordinary seeder V from 7.7 to 10.8 km/h can be considered the best, since at these values the unsatisfactory spreading of seeds per unit length or seed spacing, the inaccuracy of the established seeding rate decreases, as well as seed crushing. When using an experimental seeding unit of a grain seeder with inclination of ridges and grooves and partitions of the grooves of a fluted roller, the uneven distribution of seeds along the length of the groove, the instability of the total seeding and crushing of the seed material decreases.
