The article attempts to substantiate the urgency of the developed bulldozer-loader with the facts of the consequences of emergencies associated with the objects of work, describes the technical, economic and overview characteristics of existing bulldozer-loaders. For a previously compiled mathematical model with a system in conveniently simplified quasilinear ordinary differential equations, the motions of the centers of mass of the working bodies with generalized coordinates and generalized velocities are described. The force fields of motion drives and equilibrium force fields are recommended and calculated. A numerical method of shooting was used, a general algorithm and a program for solving the problem were compiled, which were implemented. The results of the calculation were obtained, showing the tendencies of the correctness of the algorithms.
