Abstract
The hydraulic control is for an implement which can swivel about a horizontal axis and is fixed to a vehicle, especially hydraulic control of the cutter assembly of a combined harvester. The mechanical assembly is supported on the ground with a residual weight. To suspend the remaining weight, one or more hydraulic pressure stores are connected into the hydraulic circuit. A separate piston cylinder assembly is so connected with the lifting cylinder that the hydraulic pressure of the cylinder (4) acts on one side of the piston while the pressure of one or more hydraulic stores acts on the opposite side.
