Purpose: to conduct a force analysis of the central movable support of wide-cut frontal irrigation machines and to provide proposals for its improvement; to consider the technical and operational parameters of such machines that affect the efficiency of their use; to assess the influence of external conditions on the irrigation machine productivity: objective (soil, relief, etc.) and subjective (cultural and ergonomic conditions, optimal selection of auxiliary equipment); to consider in detail the nature of the water supply system operation in the form of a flexible pressure hose of the irrigation machine and to calculate the resistance forces, that compose them, depending on the conditions of occurrence along its transferring.

Materials and methods. When substantiating the technical and operational parameters of the design, a scientific method for calculating the traction load on the structure of the central support of wide-cut frontal irrigation machines from the water supply movable pipe, was used. The component of the resistance force to the movement of the flexible hose across the field is its friction against the ground, it mainly depends on the slope direction of the microrelief of the irrigated area and soil moisture.

Results. The total value of the resistance force to the transferring the pressure hose across the field is one of the determining factors in the selection of structural elements of the central support of the machines under consideration, it is equal to 7958.94 N. Its component in the form of friction force is 5971.99 N, the gravitational component is 1986.95 N.

Conclusions. The magnitude of the traction developed by the machine units for movement and overcoming the resistance forces allows optimizing the process of selecting a reliable material, the metal structure profile of the central articulated support and the structural units of the traction equipment. The study of the technology of irrigation equipment operation makes possible their further improvement and creation of a reliable material and technical basis for the elements of irrigation systems.
