Pulling hydraulics for chipper, why do I need a switch?

[FarmerCliff]

Hi,
I have a Kubota L3800 and I need to add hydraulics to the rear to run a chipper, why can I not "T" a pressure line and "T" a return line and use that?

The dealership says I need $1,200 in parts and a switch.

I do _not_ intend to run the bucket and chipper at the same time. The bucket has 3 lines going to it marked white, yellow, and green. I believe the yellow and green are sources so the tilt and lift can both run at the same time and the white is a return.

Barring adding a "T" I do have a switching block to add open and close for a grapple, could I just use one side of that?

Please feel free to berate me, I am a total newb at hydraulics

Thanks,

You can run the "out"from the loader valve to the "in" on the second valve. Then plumb the out from the second valve to wherever it goes now. Now that's the old school method. These new valves and hydraulic systems may make that difficult.

Your dealer is full of it, if you know what I mean.

If you tee into an open center hyd system, the flow will take the path of least resistance. Not good.

You want a series flow path. One valve feeding the next valve and so on.

If your tractor is open center hyd, you can run a line back to the rear from the loader PB port, and then return the chipper OUT flow to tank. When you remove the chipper, return the flow path like original.

For my L4330, the expensive OEM Kubota "kits" included a hydraulic take-off block for the top of the transmission housing, so that existing FEL hydraulic plumbing stayed undisturbed. And an expensive Kubota-sourced control valve and termination/return block for the other side of the valve. And an expensive fabricated control valve lever to exactly fit, and expensive Kubota-sourced exact-fit hoses and rear connectors and mounting block/bracket.

All $$$$, but nice to have everything exactly fitted and integrated in.

Just wanted to say I did get my power beyond figured out, Thanks to all your help.

I added the block with solenoids to run a grappler and only connected one side to a simple on/off switch. When the hoses are hooked up I flick the switch and fluid coming back from the loader goes back to the chipper. I had the hoses built long enough that I could simply re-route them to the front to run a grappler later if that ever becomes something that I want to do.

Thanks again for all the help.
