The paper presents the results of the calculation of stresses and strains of the cultivator stand structure with a flexible tubular element under loading with internal pressure and external force. For research, we used the finite element method, implemented in the program “ANSYS”. The tasks of building a grid model of a tubular element were solved, the displacements of the free end and stresses under the action of internal pressure were determined, and the maximum allowable pressure value was found. The horizontal component of the impact force of the soil on the cultivator, at which buckling occurs, is determined, and the influence of the section shape on the characteristics of the cultivator stand is investigated.
