Loader Kubota BX23S loader raises extremely slow sometimes not at all

[polarred21]

Are all loader functions slow? Does the loader valve have it's own relief? Just thinking out loud.

Anyone got a hydraulic schematic?

Yes, all loader functions are slow or low power. Even when using the grapple instead of the bucket. No relief valve. Been emailing back and forth with the dealer as well.

Okay, well sounds like you have the experts on the line and wishing you luck. I am not an expert on these tractors but do have a handful of hydraulic background so was curious.

When you used the tractor last, what were you doing with it and what equipment was being used?

When you mentioned that it seemed the backhoe worked fine, did you verify the outriggers will pick up the tractor and will the backhoe actually dig?

Did you find this video (larger Kubota) and read all the comments? Seems a lot of good experiences here:

Thanks for the video link. I had not found that one yet. Tried it, but doesn't seem to do the same thing. Curling and raising goes slower. The outriggers work fast and lift the tractor. Even the loader will lift the tractor sometimes. Then other times not. I'm still thinking that its either something with the 3rd function OR maybe something with the loader. Last year the loader had to be replaced by the dealer under the insurance plan after it twisted while lifting and wouldn't re-attach to the tractor. Dealer is picking it up Monday morning. I'll post the results. Thanks again.

I was also surprised to find a free service manual available. It takes a little bit of time to sort through this 511 page manual, but it has very detailed information for the tractor and the hydraulic system.

Good luck.

WE HAVE A WINNER!!!!!

Well, the dealer picked-up the tractor and brought it back the same day. The problem? A malfunctioning quick-connect valve! Replaced and working perfectly now!! The best part? It was all covered under the warranty!!!!

Thanks everyone for helping me figure this out. Hopefully, this will help someone else that may have this issue.

:cool2:

Thank you polarred21!! This is a great thing to have on-hand.

For future reference, you can also test the hydraulic pressure and add shims to bump it up if it isn't to spec. This kit comes with pressure tester and a set of shims.
