3-Point Hitch Operating 3PH with Power Beyond

[LouieJunior]

I just had my dealer add Power Beyond kit to my JD4105 CUT. It will be used to operate my 3-Point Log Splitter. (Previously, I hooked up hoses to my loader QDs and Bungee tied my joystick.)*

I hooked up the splitter and soon learned the 3-point hitch will not operate with the hoses connected. If I disconnect the hoses, the 3PH becomes functional again. Is this correct?

Yes it's correct, but: The PB kit is mainly designed for operating a backhoe and with that you don't want the 3PH active. There are two returns, one feeds the 3PH and is in the "loop" when nothing is attached, the other goes directly to the tank bypassing the 3PH and that is where you your splitter is connected now, so you need to change the QD's so it is plumbed inline with the 3PH.

I probably didnt explain that well?

Probably just need to re-plumb so that the PB circuit goes to the 3-pt. Normally the 3-pt would be the last item in the PB circuit.

Are there multiple ways to connect the Power Beyond? I have one on my 2320 I use for my 3 point splitter and it doesn't affect the 3 point operation. Mine is dealer installed also.

Head back to your dealer and ask that it be corrected.

Are there multiple ways to connect the Power Beyond?

Yes, on the 3 and 4 series.

Now that I am at my PC, let me elaborate a little, take a look at this drawing from JDP:


For the 3PH to work, the splitter must be plumed into the "loop" that is connected when the backhoe is not plumbed. If the fluid is returned directly to the tank via fitting #12 than the 3PH will NOT work.

The attachment isn't working for me.

Sorry, fixed.

So, my splitter return flow needs to go into fitting 8 rather than 12 - making the same loop as the small hose used when the implement is not connected?
