The sowing unit is one of the most important working bodies of the drill. It is used to select from the total mass of a certain number of seeds and the formation of their output flow with the specified parameters. Therefore, the advantages and disadvantages of seeders, in terms of the quality of seed distribution in a row and general in the sown field, are mainly determined by the work of sowing machines. The research was carried out to develop a model of random packing of seeds of small-seeded crops in the tank of the sowing apparatus of the selection drill. The research was conducted based on numerical simulation in the software package of the CAE-system Simcenter STAR-CCM +. Because of research, the mathematical model of casual packing of seeds of small-seeded cultures in the capacity of the sowing device of a selection seeder is developed that allowed defining the equation of regression of its density from the effective diameter of seeds and coefficient of variation of this diameter. As a result of research of process of work of the batcher of the sowing device of a selection seeder regularity of change of its throughput from an angle of inclination of a gate, type of a form of executions (triangle, semicircle, rectangle) in the form of a polynomial of the third degree are received. It is established that the choice of the triangular shape of the dispenser allows for ensuring the highest accuracy of seed dosing.
