Power Beyond Connections

The SCV and rockshaft valve stack can be adapted to provide for remotely connecting hydraulic functions to the tractor hydraulic system. Your John Deere dealer can supply parts to provide port connections and divert the neutral flow using plug (A).

Power beyond connections must be used when operating a hydraulic orbital motor with the tractor hydraulic system.

IMPORTANT: If hydraulic orbital motors are used without power beyond connections, the hydraulic oil will overheat.

Be sure hydraulic functions to be connected are compatible with open center hydraulic systems of:

• 5210 and 5310 3-cylinder: 43.2 L/m (11.4 gpm) and 19 685 kPa (197 bar) (2855 psi) capacity
• 5410 and 5510 4-cylinder: 60.2 L/m (15.9 gpm) and 19 685 kPa (197 bar) (2855 psi) capacity

The maximum hydraulic system pressure will be limited by the tractor main relief valves and cannot be increased by remotely connected valves (external relief valve). External relief valve is not required unless a lower relief pressure is required.
