Backhoe Side to Side -- Stuck?

[TWD]

I was digging a hole with my Kubota m59 Backhoe and suddenly it went to the right (when facing rear) as far as it could go, and is holding itself there touching my stabilizer.

I cannot reposition it.

I came back the next day and it had no problem, started up centered, and it stayed there for my next 1-2hr project.

Fast forward a day later I needed to go do another project and I get 100' away driving and once again it goes far right max position, and now it won't center or let me center it.

I popped off the cover to see the controls and nothing is sticking or getting hung-up that I can see.


Position sensor? Valve? Dirty Screen? I have no clue what this could be but it seems to be either "on" or "off" no in-between bleeding off causing it to slowly move.

I do not know the M59, but you may have a position sensor, and semi-automatic swing control. My old Kubota B20 had that, which was pretty low-tech, but did feature a couple of solenoid valves and just some contact fingers to detect the position.

The owner's manual talked about it, so you don't have to have a service manual, tho I would still get one.

Glad Kubota dumped it on the B21. Lots of M59 owners on TBN.
