The implement control valves are assembled in a valve stack. The valve stack for the hydraulic system is located below the platform in the right side of the cab. If the machine is equipped with an attachment additional control valves are added to the valve stack. The number of additional control valves in the control valve stack depends on the type of attachment that is used. An attachment can include a ripper or a winch.
If the machine is equipped with a ripper then the valve stack includes the following valves.
- Ripper tip control valve
- Ripper lift control valve
- Bulldozer tilt control valve
- Bulldozer lift control valve
- Steering control valve
- Inlet manifold and main relief valve
If the machine is equipped with a winch then the valve stack includes the following valves.
- Winch control valve
- Bulldozer tilt control valve
- Bulldozer lift control valve
- Steering control valve
- Inlet manifold and main relief valve
