The problem of intensifying soil development by modernizing work members of earthmoving machines is associated with changes in cutting angles and blade installation angles. The forces developed on the working equipment of a bulldozer depend on the kinematics of their moving elements (hydraulic cylinder rods), since in the considered blade design, the intensification of soil development is achieved by changing the positions of each section by extending sections with hydraulic cylinders, which affects the change in the forces developed in them. The study objective is to justify operation automation of soil development by the work member of a bulldozer blade with extendable sections. The problem that the paper is dedicated to. Automatic changes in the positions of hydraulic cylinder rods during operations by the work member of a bulldozer with extendable sections are considered, depending on changes in cutting angles and installation angles of the blade section in the direction of the machine movement. The research methods are based on the basic principles of the theory of soil development by the work members of earthmoving machines, and on a systematic analysis of operation automation of machines for basic technological purposes. The novelty of the work. An option for automating the operation of a bulldozer with extendable sections is proposed. The study results. The study is aimed at substantiating the automation of the soil development based on the nature of changes in the parameters of the hydraulic cylinder rods, the angles between them for the improved design of the bulldozer blade when changing cutting angles, installation angles in the direction of the machine movement or when extending sections with a straight blade position. Conclusions. The possibility of developing operation automation of soil development by the work members of earthmoving machines in the digging mode, which is the most energy-intensive, depends on the productivity and efficiency of the equipment when changing the positions of the work member relative to the surface of the developed soil, taking into account the efforts of soil development, cutting depth, which must remain constant for the steady operation of the machine.
