The article presents the geometrical parameters of the scourges of the threshing drums of combine harvesters. Three main factors of crushing and microtrauma of oilseeds are established when sunflower thrashing. The positions of the sunflower in the threshing chamber, and the forces acting on it are considered. They are obtained expressions for the law of change in the impulse of the threshing chamber system during basket threshing, determining the number of blows of pests per unit of time, the time of the impact of the scourge on the threshed mass, the supply of baskets to the threshing chamber.
