The parameters necessary for driving the working bodies from the sowing section of the precision seed drill are substantiated. With these machines, the seeder disc is mechanically driven. The seeds are retained in its holes on seed disk by the force created by the vacuum. The stepless mechanical drive allows for the realization of different sowing rates (pieces of seeds per decare). The force required to hold the seed to the sowing disc varies to some extent due to differences in weight. In the present work are researched and determined the power for driving the sowing disc and the pneumatic units for creating a vacuum. The obtained results were used to determine the elements of a device for mechatronic control of the operation on a seed section from a precision seed drill.
