Loader rolls back when front edge is set on ground

Mine doesn’t roll back. It stays exactly where it is placed.

Mine remains angled and I can lift the tractor off the ground with it.

Sound like you may have leaking valve or cylinders that will not hold hydraulic pressure on the down angle of bucket...

It's the control valve leaking.

Not unusual for these.

If you replace the o-rings inside, it will stop.

I would ignore it until you get external leakage.

Thanks for the replies. Dealer replaced loader valve and repacked cylinders, still doing the same thing. They now say I’m not operating it right. Going to dealer tomorrow so they can show me what they are talking about.

Please explain the exact scenario. Are you parking it for an extended amount of time in that position?

On any front end loader that I've ever operated, the bucket will stay in whatever position it is in when you take your hand off the control.
Typically the bucket stays in a fixed position - any position - and most can then lift the front of the tractor by putting down pressure on the loader arms.
Is yours not doing that?

You kind of have to have that FEL ability it order to use the backhoe in your picture. The FEL bucket becomes your front stabilizer.

If the dealer replaced valve and repacked cylinders I’d say they were guessing at the issue and didn’t do proper testing to rule out the valve or a cyl.
I’ve seen the OEM seal kits that MF uses on their cylinder rebuild kits and they are plain Jane orings and backup rings. If you go to the dealer see if they will let you see the exact type of seal kit packages they installed and take detailed pics and post here.
My hunch is substandard seal kits. They can be upgraded (but not at the dealer).

Exactly. People don't fully explain what they're asking about and others jump in and postulate on things that may not be relevant.

An update to my loader problem. In order to make the bucket stay in place the tractor has to running above 2000 rpm. Factory rep claims that the rpm has to be that high for the pump to put out enough pressure to the back side of the cylinders to hold them in place. While this doesn’t make sense to me it does keep the bucket from rolling back.

gc1723 I use doesn't roll back.
if I leave it curled up with bucket itself a little in air it MAY, over the day, bleed down and uncurl a bit. if I leave it with edge on ground it just stays there.
you've never accurately described your issue so who knows.

I’d say maybe your factory rep needs a refresher course on hydraulic troubleshooting. Your pump should be putting out full pressure even at idle (unless the pump is bad). If it requires revving up to produce full pressure then a flow/load meter will be needed to test pump properly. Even with a bad pump the cyls should still hold a load with valve spool in neutral.
