The signal oil from the blade lift is forcing all the signal check valves and compensator valves in the implements to be in the closed position. The signal oil pressure for the steering is lower than the signal pressure for the blade lift. The ball in signal resolver valve (11) moves in order to direct the pressurized signal oil to the pump control valve.
The implement circuits are composed of four main components:
- Hydraulic pump
- Combination valve
- Implement control valves
- Cylinders and circle drive motor
The hydraulic pump transfers oil from the hydraulic tank to the implement cylinders and to the circle drive motor through the implement control valves. The combination valve provides the priority for the steering circuit and transfers load signals for the implement control valves to the hydraulic pump.
