成果简介	NOVELTY - The system has a hydraulic cylinder (14) that is associated with a soil working implement (12) with a first connecting unit (24) and a second connecting unit (26). A control unit is in data communication with a directional control unit and an electrohydraulic valve assembly. A hydraulic channel (28) interconnects the directional control unit, the electrohydraulic valve assembly and the hydraulic cylinder. The directional control unit diverts a high-pressure hydraulic fluid to the hydraulic channel for connecting one of first connecting unit of the hydraulic cylinder through the electrohydraulic valve assembly and second connecting unit of the hydraulic cylinder. The directional control unit raises and lowers the soil working implement, where the directional control unit is a solenoid valve. USE - Electrohydraulic system for a soil working implement i.e. land leveler (claimed), in agricultural and construction applications. ADVANTAGE - The system uses the control unit to provide signal to the directional control unit and the electrohydraulic valve assembly based on signal received from a user interface, a displacement sensing unit and an altitude sensing unit, so that the soil working implement can be raised and lowered precisely. DESCRIPTION OF DRAWING(S) - The drawing shows a perspective view of a work vehicle that is attached with a soil working implement. 10Work vehicle 12Soil working implement 14Hydraulic cylinder 24, 26Connecting units 28Hydraulic channel
