A review of technologies for sowing non-loose seeds of forage plants shows that seeders and devices that fully meet the requirements of agricultural technology have not yet been created. The available tools do not provide a stable sowing of seeds and their uniform placement in the field, so the distances between the nests are not the same in a row. The authors recommend designing the sampling drum for an innovative universal seeding machine with measuring grooves that ensure the same distance between the seed nests in a row, corresponding to the agrotechnical requirements for seeds. The main requirement when creating a seeder was the need to determine the number of grooves that determine the distance between the nests at different speeds of the unit. In addition, it is also required to ensure that the measuring grooves are filled with the required amount of seeds, which depends on the speed of rotation of the sampling drum. Based on preliminary laboratory experiments and theoretical studies, the optimal parameters of the sampling drum were determined: the diameter of the sampling drum is 100 mm; the speed of rotation of the sampling drum is 8-15 rpm; the number of measuring grooves – 10-12 pieces. These parameters at a speed of MTA -1.44 m/s provide the distance between the seed nests in a row and are 0.5-0.7 m.
