Knowing geometric and aerodynamic features of sown seeds, work parameters of a pneumatic single-grain drill were calculated. The selection of the proper drill and calculation of its work parameters is also possible. The verification of obtained results was performed with the use of a computer method for testing the drill work quality. The carried out measurements of sowing and elaborated method allowed us to assume that there would be a possibility of using single-grain drills for sowing forest tree seeds.
