B2320 deck won't lift

[ryan440]

Hi everyone. I just found this site, hope someone can help me out.
So I have a B2320 about 10 yrs old. Recently the mower deck and 3pt hydraulics stopped lifting. I changed the filters and fluid and still nothing. Front loader hydraulics work fine. I believe there are 2 pumps, I imagine worst case 1 pump is shot. How should I proceed?
Thanks in advance!

I believe one pump is just steering and brakes, the other pump is hydraulics. Get a WSM for your tractor, try the dealer or here. https://www.kubotabooks.com/AutoIndex/index.php?dir=Tractor Owners Manuals/

I think one power steering pump, one for the rest of the hydraulics. So in theory if the loader is going, the 3pt should too. So there's hope that it's something else broken.

I hope so. Any ideas anyone? Anyone else have this happen and if so what was it. I am fairly mechanical but unfamiliar with hydraulics

I don't know your machine specifically but some (like the BX) have a control knob for the drop speed of the 3pt and deck. It's down between/behind your legs (calves) normally.

If it's adjusted in too tight, the deck and 3pt will not move.

Yes, I think your tractor has the same drop speed control knob but not certain. Good place to start.

I might also suggest pulling the mower off, in case something is binding in the linkage.

Do you hear any noise when trying to lift, like the system going to pressure relief?

Check the linkage on the left rear side of the tractor. There is a adjusting rod and it connects to the lift arm. It connects to the lift arm with a bolt and TWO nuts. Make sure this bolt is not pinching or binding. It fits a little loose so it can move, thus the TWO nuts to retain the bolt.

They will still raise, the Rate of Lowering speed knob only affects the lowering.

The deck linkage on a B series is completely different than a BX series.

I'd trace the linkage back to the lift arms themselves, where they come out of the transmission body. Disconnect all that, and check there's no binding in any of the linkages, see if the arms will lift on their own without the rest connected. Beyond that I suspect you're looking inside the transmission to see why they're not lifting. Although I think that machine has position control, so it's possible for the feedback link to get out of adjustment?

So I 1st worked on this about a month ago and am just getting back to it now. I do recall messing with the lift knob and made no difference. I removed the deck and linkage still will not lift,they aren't bound up or stuck.
