Traction Kubota b2231 100 hours - power steering fail

[maciek8791]

Hello,

I have my new Kubota b2231 since 5 months now. I am very happy, it's a fantastic machine, but there is one problem which I see recently.

The trouble is that when the machine is not moving, I have a problem with the power steering - the wheels are not willing to rotate and I hear the sound of the pump having too hard time.
I join a small video so You can see what I am talking about.

Kubota b2231 steering wheel problem - YouTube

- This happens when machine is standing down
- It can happen just once during the whole day, or not at all
- The problem dissapears immediatelly when I move the tractor forward or back - so at next stop, it should be OK

My dealer replied, that this is a normal issue due to the fact that I have the FL and therefore the solution is to use the ballast in the back.
Which is total b-s, because this happens also with 300KG in the back and empty bucket (as You can see on the video bucket is empty)
Do You guys have any idea what could cause the problem? I suspect that it could be the Orbitrol valve. I am really puzzled now, because theoretically I cannot do anything - the tractor is new (warranty), so I cannot repair it myself and the dealer says it's fine... Really no idea what to do.

The problem is not affecting the daily job honestly - I just move the machine and its fine. If I drive - absolutely no problem with power steering.

What do You guys think?

I don't know I never turn the steering wheel on anything unless its moving, less strain on the steering components . But it does not sound right.....

Your tractor is still under warrantee - have the dealer fix this situation. My power steering moves the wheels - left/right - just as easily whether it is standing still or moving. The power steering pump never makes as much as a whimper. Your dealers explanation - it's because you have a FEL - pure Bull Sheet.

I have an FEL and VERY heavy grapple on the FEL.

However - I will not make major wheel movement with a heavy load in the FEL and the tractor being stationary. It's a whole lot easier on the system to have the tractor moving when major left/right wheel movement is made. View attachment 679205

Does the steering use its own reservoir? What fluid should it use?

I would throw a fit. That usually works.

At a minimum I would make certain the situation is documented in kubota痴 database with their explanation that it normal behavior clearly documented. This will help in the event it fails completely after warranty period.

My guess is they will be unwilling to document their response clearly in an official (legal ) way.

I do not own or have design responsibility on this model to comment on how it should work. My expectations are the wheels will respond to steering wheel input.

Good luck.
