In the process of pre-sowing tillage, cultivating shovels on various stands are widely used. The type of stand affects the energy and quality indicators of the process. However these stands have one significant drawback: with the increase in the strength of soil resistance, there may be buckling of the stand, which leads to a decrease in the quality indicators of the process. To stabilize the depth of cultivating the soil with cultivating shovels on elastic stands, while maintaining the vibration effect, is possible to achieve through the use of cultivating stands with variable stiffness, made on the basis of a flexible tubular element. The work presents the results of calculating the stresses and strains of the design of the proposed cultivator stand under loading by an external force. For research, the finite element method implemented in the ANSYS program was used. To simulate the movement of a cultivating shovel in the soil, we assumed the following - the treated soil was considered as a continuous medium. The tasks of constructing a grid model of the tubular element were solved, the horizontal component of the force exerted by the soil on the cultivator was determined, at which buckling occurs, the work of the cultivator shovel in the soil is modelled and the permissible speed is determined at which buckling of the flexible tubular element is eliminated.
