摘要：
A hydraulic circuit for lifting and floating a tool supported by a tractor for agricultural uses, comprising at least means (2, 3) adapted to pressurize the fluid contained in the hydraulic circuit, two actuators (8, 9) actuated by the pressurized fluid and adapted to lift/float the tool, and means (4) which are adapted to control the flow of the pressurized fluid into the hydraulic circuit, characterized in that it further comprises a pair of reservoirs (10, 11) for the pressurized fluid, means (6) which are adapted to produce a preset value of the pressure of the fluid inside the hydraulic circuit, and means (5) which are adapted to automatically restore to the preset value the pressure of the fluid inside the hydraulic circuit.
