Seven are cylinder circuits and one is a hydraulic motor circuit for rotating the blade circle about the drawbar. An implement system can accommodate as many as fourteen implement control valves. The individual control valves regulate the operation of each implement. Operator control levers for operating the implement control valves are located on the operator console on both the right side of the steering wheel and the left side of the steering wheel.Note: Some of the motor graders may have different implements. The number of the control valves in each valve group may vary.Note: When you replace an implement control valve use the same part number. This will keep the control valve and the cylinder matched.Note: For additional information on the hydraulic system, refer to the hydraulic schematic for your machine.
