The equation of shock interaction of the vibrating digging working body with the body of the sugar beet root, fixed in the soil, which occurs in the process of vibratory digging of the roots, is made. Based on the shock interaction equation, the shock pulse and the maximum shock force that occur during this interaction were determined, which allowed to further assess the degree of damage and knocking out of root heads in the process of vibration digging of sugar beet. From the conditions of non-damage of root crops the expression for definition of admissible frequency of fluctuations of the vibrating digging working body taking into account its design parameters and translational speed of movement of the beet harvester is received. Based on the obtained equations describing this process, the optimal values of the kinematic and structural parameters of the working plow for vibration digging of sugar beets are found.
