This study aims to determine the conditions for soybean seeds to be able to move on the sowing disc when the centrifugal force created is much smaller than the friction force and the travel time of the seed so that the number of seeds required in the seed collection area is maintained and facilitates for the getting seed of the disc hole. By method of modelling and theoretical analysis of kinematic and dynamic, we have been identified: the angle of the straight directive vaneis fixed to the horizontal position greater than or equal to 70 degrees 50 minutes, the seeds movedalong the directive vaneand the ratio of the time the seed moves through the directive vane length with the disc's rotation time is a constant (k = 0.23), independent on the rotation speed of the sowing disc.
