FIELD: transport.
SUBSTANCE: invention relates to handling equipment, mainly, to agricultural machinery. Drive hydraulic system comprises boom lift hydraulic cylinder and column turn hydraulic cylinder with pressure lines communicated via differential double-flow controlled restrictor that adjusts working fluid flow into column turn hydraulic cylinder chambers subject to pressure in boom lift hydraulic cylinder pressure. Hydropneumatic accumulator may be connected to boom lift hydraulic cylinder piston end to equalise overpressure at switching on boom lift drive circuits.
EFFECT: decreased inertial loads, lower vibration.
