FIELD: automobiles, tractors and other self-propelled machines working under low temperatures, in scarcely populated areas and under extreme operational conditions. SUBSTANCE: proposed positive-displacement hydraulic drive has hydraulic accumulator, hydraulic tank, hydraulic machine kinematically coupled to shaft of engine, controlled distributor, two-mode regulator put ahead or after rotor hydraulic machine. EFFECT: improved lubrication conditions and process of formation of mixture, enhanced reliability of start thanks to provision for optimum law of change of rotational speed of engine shaft depending on number of its revolutions. 2 cl, 4 dwg
