First post - have a 2009, b2920 with a la364 loader, hydrostat with hydraulic issues (local kubota dealer couldnt initially figure out) - bucket tilts up/down ok, wont move down but will float down, eont go up unless barely pull back lever, and 3pnt wont work at all - had leaks in 2 hoses going to bucket that i replaced but used old quick connects - ideas on what could be wrong? I think one of my bucket hoses drips when disconnected… could quick connects be causing these issues? All started when leaks got so bad the bucket wouldnt work and still have same issue - thank you!

Power beyond issue.
Normally a bad quick disconnect on the Power beyond line.
This causes erratic loader operation and No three point operation.
Just to make sure, it doesn't have a backhoe loop does it?
If it does you need to check that loop too, as it's part of the Power beyond circuit.

Thanks, I dont know what the power beyond line is and it’s been hard to find info online… been trying to learn more about the hydraulics…
drawing or video or idea of where to look?
i do have a kubota backhoe that i use sometimes but havent hooked up in a while, i have been mowing quite a bit last couple years with my finish mower

Ok diggin into this model the PB circuit is almost all internal, but the one part is external is the BH loop
You need to look at these connections.
To start with try disconnecting and reconnecting the BH loop.

Need Help Connecting Hydraulic lines from BT601 Backhoe to BX2670
Hello, looking for assistance with connecting hydraulic lines between aBT601 backhoe to Kabota BX2670 tractor. I have attached pictures, and color coded the lines. Blue, white and yellow come from the backhoe. The yellow is on the left side of the valve body and blue and white on the right side...

There is no bh loop that i can see on the tractor… the one hose that comes straight out of the loader valve is what you connect to the bh - im not using the bh and this issue is without using or hooking up the bh - could it be a couple quick connects to/from bucket and the one that i would hook up to the bh?

How long have you had this issue?
How long has the BH been off?
The connections to the loader could have an issue on the operation off the loader, but would not have any bearings on the issue with the three point.
Have you ever turned the three point speed control under the seat?

This is the BH loop.
You need to have those 2 connected together when the BH is off.
Has this line been disconnected since the BH was removed?
If it has then there is a very high likely either the Pressure relief valve will be damaged or the possibly the pump.
If it's been connected try disconnecting it and reconnecting it.

Two loader hoses were leaking, I put it off until they leaked bad and this issue started and the 3pnt stopped working at the same time - I replaced the hoses and changed the hyd oil and filters (prbly about 2 mnths ago) - i haven’t used the bh in a year or more
i have tried turning the knob under the seat and noticed that didn’t affect the 3pnt at all, which it used to
i’m sorry but not sure - this looks like the bh again but i havent used the bh for well iver a hear and this issue started with my loader hoses leaking and got really bad leaking and then started not working and then 3pnt stopped working - the bh hasnt been connected in well over a year

The hose is on the tractor not on the BH.
Simply take a picture or two of the back of the tractor and I'll point it out.
If the BH outlet was not looped the 3pt and loader would not have been working.
But that loop may have failed causing your current problems. You need to find the loop, understand it, and verify its properly connected. Extended periods of operation with the loop disconnected can easily cause expensive problems.

Here are 3 pictures of the rear hose that i would hook up to bh, that back area, ans the loader control valve (i think)
i also re-read what kubota said and they said for bucket they would need to take apart and inspect the loader control valve and for the 3pnt not going up, they would take apart and inspect the position conteol valve
thanks for any help!

Your power beyond circuit is liiely blocked and there is nothing wrong with the loader or 3pt. You need to find where its blocked and fix it.
Dan
Can you or someone show me the power beyond circuit so I can troubleshoot disconnect and clear out?
The backhoe loop is part of the power beyond circuit. Disconnect and reconnect that hose and see if that helps.
If not remove the male tip on the hose and stick the end of the hose in the transmission oil filler. Start the tractor and you should get a solid flow of oil. If so test the loader.
Dan
Download the WSM and study the hydraulic circuit schematic.
