In the article, in accordance with the task of research, the influence of the parameters and operating modes of the blade and separation rod part of the working body for the excavation of potatoes and mechanical properties of the soil on the change of its mechanical properties, its dissolution and the possibility of fracture of continuity, which will provide better conditions, is analyzed. Sowing soil agro-gates through the bar section of the separation surface. In the first approximation, the working body when entering the soil is represented as a hyperbolic paraboloid. The equation of the surface of the lemma and the surface in which the separating rods are placed is implicitly recorded. In order to establish the rational values of the coefficients of this equation, which determine the geometric shape of the lemeh's surface, its curvature, the curvature of the surface in which the separating rods are located, the connection of the di-tminical quantities, in particular the stresses in the soil, depending on their mechanical properties properties and geometric parameters and operating modes of the lemmas.  These dynamic quantities are components of stress in the soil sediment. These components are determined by dependencies that reveal the relationship of stresses with strain rates. In order to obtain a visual picture of the influence of the parameters of the darned part of the digging working body on the direction of soil changes, contour graphs of the isolines of the magnitude of the form of its intense state were obtained in terms of the influence of the lemmas on various parameters. Charts are obtained using the application of Mactematica It provides the values of the coefficients that are included in the equation of the surface of the surface and the surface in which the separating rods are distributed are changed. The analysis of the graphic dependences obtained allowed to establish the rational values of the coefficients of the equation of the surface of the lemma and the surface in which the separation bars are determined, which determine the geometric shape of the surface of the le-fur, its curvature, the surface of which is the rods of the separating part.
