Abstract:
An agricultural implement includes a transversely extending frame forming a first, a second, and a third frame section. A hydraulic control system controls a raising or lowering movement of each frame section. A first actuator and a second actuator are coupled to the first frame section, a third actuator is coupled to the second frame section, and a fourth actuator is coupled to the third frame section. A first control valve is fluidly coupled between a fluid source and the first and second actuators. A second control valve is fluidly coupled to the third 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 third actuator, and the fourth actuator in series and a second flow path fluidly couples at least the third and fourth actuators in parallel with one another.
