Kubota KX 080-3a service valve stuck on

[Muckster]

Evening folks
I jumped in the digger this morning and as soon as I pressed the button to energise the service lines the tilting bucket powered to one side and I couldn’t make it release!

Never had any trouble before and had used it for a full shift yesterday with no issues.
It seemed like it was getting a false signal from the proportional control, I don’t think the valve was stuck as it was in a neutral position when I parked up.

Cheers
Martin

Can only be the valve stuck really, if you can change the pipes over on the tilt and see if it goes to the opposite side!

Is it a proportional roller or push button?

It’s the proportional roller.

The weird thing is that it was in the neutral position when I parked it up! That’s what’s confusing me….!
Sibiu expect it to be stuck in that position if any….

A button could be stuck even if you use you tilt bucket off your prop roller.

Had it got the constant flow option that the new kubotas have?

Never used it but I believe button on front of right stick is constant flow

And that could be the problem!

First thing I'd do is disconnect the plugs on the solenoids, this will eliminate the wiring/electrical side or the valve

Thats where I was going with it

I stand enlightened, and with new knowledge.

Ah, that’s exactly what it seems like. I’ll try that first. Thanks all
