MMM arms dropping on 1026R

Just wondering if other 1026R owners are experiencing the MMM hydraulic arms dropping down (when mower is not on). On mine, have to keep raising them back up, every couple hours or so. Have the SCV locked, so am not accidentally lowering the arms.... apparently have slow hydraulic bypass, seep or some such?

I am not sure on the new machine's, but with the independant lift on the 2x20 series it is quite normal. Is there a knob/selector that you can lock them up with?
It's kind of the "mystery" option. You can see a wire called out to this non-existent switch in the wiring diagram. There's a plug below the dash for the switch. However, there's no switch listed in parts. There's nothing mentioned in the manual or any other place on the Deere site.
I have no idea...maybe a EU option like the cabs?

So it's normal for the deck to lower slightly.

Yup, discussed a lot on the site if you search.

Very simple, remove the MMM to do any FEL work, it's so east and you won't loose the ground clearance or risk damaging the deck while your paying attention to the loader.
I've found that you must disconnect the hydraulic line from the yellow terminal going to the mower and hook up the corresponding yellow line from the loader otherwise the "recirc" won't work right. (Bucket won't drop quickly).
Regen or regenerative is the proper term.

But once the hydraulic line to the mower is disconnected it's impossible to raise to "full up" after it gently floats down a little from the locked position.
Again, just remove the MMM for FEL work...
