FIELD: transport mechanical engineering.
SUBSTANCE: system comprises electric means for changing working volumes of pumps and hydraulic motors and pickup (60) of the speed of rotation of the shaft of the pumping station. The electric circuit has variable resistor (61) and switch (62) interconnected between pickup (60) and electric means (40-45) and controlled by pedal (63) for supplying fuel to the engine, resistor (64) connected in parallel to the switch, and threshold control unit (67). The electric circuit also has threshold control unit (80) interconnected between the pickup and electric means (54-59), with the threshold being controlled by pedal (63).
EFFECT: improved quality of control.
