I bought this tractor at the end of 2018 and love it...I bought it with a FEL and a BH77 backhoe installed shortly after I installed a hydraulic 3rd function valve. I have never hooked up anything besides the backhoe to the the rear. I bought a wood chipper this passed weekend and installed it, it ran like a champ... but when I tried to raise the 3 point it wouldn't do anything... I read through the manual and made sure I tried all positions on the raise and lower lever and I made sure to open my flow knob under the seat. I removed the chipper to do some more looking around and I can grab the 3 point and move it up and down ...almost as if it were not pressurized or in float mode...not really sure where to start... any suggestions?
2018 L3901 3 pt will not pressurize

When you took the backhoe off did you take the long hose on the tractor and plug it into the female connector on the tractor to complete the loop?
Good call, and yes I did, forgot to mention that

I would double check that their are all the way together. Based on what you are saying it sounds like the loop isn't complete.
even when I have the backhoe hooked up and its working it still wont lift

I looked up what a feedback rod is, and I saw a good blown up diagram and instructions on to adjust it...when looking at the diagram it looks like the feedback rod is mechanically connected to the control lever...is that the case? because when I move my control lever, the feedback rod does not move...also in the instructions on adjusting it says to adjust the relief valve...but nothing in the picture pointed to what that is...anyone have a pic of said relief valve?

Can you post some pics of your loader valve, the hydraulic block under the right floor board and hoses? Is it possible the dealer didn’t plumb it right? I would think you would have other issues but maybe somebody might see something. I would be surprised a machine that new would have an issue like that, but anything is possible. I have a GED in hydraulics from OTT, but I just installed a bh77 on my tractor a little over a month ago. My tractor pretty similar to yours I believe.
The feedback rod should be connected to the left lift arm if you are standing behind the tractor. It is number 160 in the diagram below.

Follow this hose to where it comes from and take a pic if you can

Those two hoses need to be swapped,your return from the loader is feeding the power beyond to the 3 pt,your back hoe return is plumbed into the tank return.
BUT... I don’t know how the third function is tied into your system. But still I don’t believe it’s plumbed right

would it be beneficial to show u the plumbing of the 3rd function,because I believe it was the way u are stating until the 3rd function got put on

Yes. Those hoses I pointed out need swapped because where the loader return is going is feeding your 3 pt and it won’t work. The only question would be if they have the 3rd function plumbed right
the one I have my finger goes to the loader valve in the other pic with my finger on it....the hose on the right of the 3rd function is the return from the backhoe

You need to swap those two hoses I pointed out earlier. The hose that your finger isn’t on is tied into the long hose to the back hoe, right?
