Beschreibung
Zusammenfassung:	The present invention discloses a hydraulic system for a rotary implement, including an oil tank, a main pump, a control valve, and a rotary motor; the oil tank is connected to an oil suction port of the main pump; an oil outlet of the main pump is connected to a P port of the control valve; a T port of the control valve is interconnected with the oil tank; and A and B ports of the control valve are connected to both ends of the rotary motor. The control valve includes a compensation valve, an electric proportional valve and an electromagnetic reversing valve; the P port is connected to a first oil port of the electric proportional valve, as well as third and fifth oil ports of the compensation valve; a second oil port of the electric proportional valve is connected to a first oil port of the compensation valve; a second oil outlet of the compensation valve is connected to a third oil port of the electromagnetic reversing valve as well as the T port; a fourth oil outlet of the compensation valve is connected to the T port; the fourth oil port of the electromagnetic reversing valve is connected to the T port; and the second oil port of the electromagnetic reversing valve is connected to the B port. According to present invention, the control valve is added to regulate the flow entering the motor of the implement to allow individual control of the motor speed.
