The problem of control of strength characteristics of agricultural machine parts by dynamic non-destructive methods of impact indentation of conical shape is considered. The quality of the most important parts is considered in terms of the set of mechanical characteristics that determine the strength, hardness, wear resistance and deformability. These characteristics should be known and be able to quickly and accurately control all parts both during production and during operation. The mechanical properties of metals are stochastic. For this purpose, a device for impact indentation was developed and a method based on the probabilistic laws of dispersion of mechanical characteristics was developed.
