This study presents a theoretical analysis of the interaction between soil and the working bodies of non-inversion deep tillage implements, namely chisel plows and loosening tines. Particular attention is given to the forces acting on the chisel shanks as they penetrate and move through the soil. The research demonstrates that the following forces play a dominant role during non-inversion soil loosening: normal force, friction force, shear (soil failure) force, and draft force. The theoretical calculations were carried out using a mathematical model that takes into account the geometry of the loosening tine and the penetration angle of the chisel, the physical and mechanical properties of the soil, and the working depth of the loosening tool as the main parameters.
