Hydraulic control system of an implement for a work machine and method thereof
An agricultural implement includes a transversely extending frame forming a first, a second, and a third stage section. A hydraulic control system controls a raising or lowering motion of every frame section. A first actuator and a second actuator are combined to the first frame section, a third actuator is coupled to the next frame section, and also a fourth actuator is coupled to the next stage section. A first control valve is fluidly coupled between a fluid supply along with the first and second actuators. Another control valve is fluidly coupled to the next actuator and a third control valve is fluidly coupled to the fourth actuator. A first flow path fluidly couples the first actuator, the second actuator, the next actuator, and also the fourth actuator in series and a second flow path fluidly couples at least the third and fourth actuators in parallel together.

In the agricultural industry, wide implements such as area cultivators and the like include a major frame and adjacent outrigger or wing frames that are hinged or pivotably coupled thereto. Each frame comprises at least one hydraulic actuatorfor raising or lowering the respective frame for proper depth control of gear. Conventional depth control techniques use parallel or series hydraulic control. With series-only control, it can be difficult to provide individual depth control of eachframe section independently of another framework sections. With parallel-only control, more hydraulic flow is frequently required for raising and lowering individual frame sections. Moreover, it may take more time to raise or reduce the individual framework sectionwith parallel-only flow.
From the present disclosure, a hydraulic depth control system is described and exemplified for providing individual depth control of each framework section independently of another framework sections and raise or lower each framework section more quicklythan traditional parallel-only control systems.
