BX-25 bucket uncurls

[Smokeybee]

This just started over the weekend. With the tractor running, the bucket uncurls on its own with no load. The hydraulic fluid was slightly low so I topped it of. The bucket is still moving on it's own.

I'm mechanically inclined but I've never worked on hydraulics or tractors. Any idea what could cause this?

Thanks- Smokey

Could be worn piston seal. If it is a worn valve in the control, you may be able to pinpoint by a slight off-setting of that control to "curl" and watch bucket.

I shattered the end of my tilt cylinder twice...Once around 400 hrs and again at 850. Check your quick disconnects for debris...

Isolate it to be the valve or the cylinder by swapping the lift for the roll at the spool valve, if the problem follows the swap then it's the valve, it the problem stays at the roll then is a cylinder issue.

Are you talking about the loader bucket or the backhoe bucket??

Its the front end loader, still doing it yesterday. Thought if I ran the tractor for a while it might work some air out of it but it didn't.
