Use SCV outlet to power 2 bank valve chest

[TomOnTractorByNet]

I have 2 x hydraulic in/outs on my 855 tractor. I don't have a power beyond circuit and the JD kit would be prohibitive here. I'm thinking of putting a 6-way hydrailic diverter valve on one of the in/outs and putting an additional 2-bank chest valve on the newly available switched circuit to power 2 additional circuits.

I'm wondering will I then be able to use the scv (together with a bungee cord) to push flow to the 2-bank valve on a semi-permanent basis when I need to use the two new hydraulic circuits.

Any issues with using the scv in this way?

Do you have a loader valve on your 855?

One issue I can see is that if you have the SCV on, the return flow from the valve is returning straight to the tank and bypassing the 3 point hitch.
As such when the SCV is on, the 3 point hitch will not lift.

I'm not sure. I have 2 x in/outs on the left hand side under the footplate that are connected to rear outlets via quick connects. These are controlled by a 'joystick' to the right of the seat that has forward/back and left/right movements. In addition, I have a 3-pt hitch lever/controller.

Ok. Understood. That wouldn't be a game changer, as I could not envisage needing to control up/down movement on the 3-pt while using the extra functions. I'd be more concerned if the SCV being constantly on would result in overheating of the hydraulic oil and/or bad effects on the system such as relief valve(s) etc.

How about stacked diverters, with two diverters and a double throw switch one outlet will get you three.
No power straight thru, activate one and flow thru it, activate the other and flow thru it all controlled by your existing valve handle.

Thanks for that. Your suggestion certainly sounds interesting. I'm not able to visualise on how the stacking would work however. I'll need to look into how that all would be put together.

If you have any links to examples, they'd be much appreciated.

That joystick would be the loader control. Can you send a picture of the connections to the valve that that joystick connects to? It should either have 5 or 7 hoses connected to it, or it could be bolted to the side of the transmission case.
