An agricultural implement includes a transversely extending frame forming afirst, a second,and a third frame section. A hydraulic control system controls a raising orloweringmovement of each frame section. A first actuator and a second actuator arecoupled to thefirst frame section, a third actuator is coupled to the second frame section,and a fourthactuator is coupled to the third frame section. A first control valve isfluidly coupledbetween a fluid source and the first and second actuators. A second controlvalve is fluidlycoupled to the third actuator and a third control valve is fluidly coupled tothe fourth actuator.A first flow path fluidly couples the first actuator, the second actuator, thethird actuator, andthe fourth actuator in series and a second flow path fluidly couples at leastthe third andfourth actuators in parallel with one another.
