Is the sound continuous? Does it change when performing certain functions. Does it change according to engine rpm or ground speed? Is the PTO lever for the rear PTO fully disengaged?

A wine could be a relief valve it's either bad or a control lever is restricted and not fully engaging or if you have remote hydraulics
you may have it engaged.
you may have it engaged.

DMW... rotational whining sound is continuous and does not change in pitch or volume when front PTO engaged or disengaged, rear PTO engaged or disengaged, or with motor speed/RPMs, nor when tractor is in motion forward or backward... the whine is consistent, as is the front steering 'chatter' (don't know an easier way to describe it) when the tractor is in motion forward or backward.

Could the 3pt control valve for adjusting the MMM height/speed have been accidentally closed? Does the 3pt work normally?

DMW... if you are referring to the lift/drop speed adjustment (knob), I have checked and tried all settings from slowest lift/drop speed to fastest. The 3-pt lift is not working at all, so the issue definitely is impacting the operations of the 3-pt system. I rarely use any implements on the rear 3-pt (occasional use of bush-hog); the MMM gets the bulk of my usage.
I am not strong mechanically, particularly with hydraulics, (I'm a 63-year old computer geek) and have to rely on a nearby mechanic for any serious work on the M-F. Looks like a return visit may be in store!

Is the valve shaft actually turning, or just the handle? It's happened before.

DMW, you ask good questions. Will put on my best glasses to be sure. 
UPDATE:
Can put hand-on-heart and confirm that the valve shaft is actually turning... did not make any difference in the sound, nor in the front steering chatter.
I must amend something I posted earlier, the pitch of the whine does change with engine speed. Volume/intensity does not change. Whatever the source of the whine, it's rotational and varies with engine speed. Apologies for the earlier misstatement.

In the parts book there are 2 adjustment knobs for the MMM. The height adjustment is mechanical for the height. The other knob controls the speed of raising/lowering. It also affects the 3pt as well. Fully closed it will stop the 3pt from moving.
#39 in the pic.
The shaft #38 threads into another shaft #30, both have to turn.

Tracking the two/separate control knobs and their intended function. The adjustments that I applied were only to the raising/lowering speed; I have not used the hight adjustment since purchasing the 1705 in 2014.

Check that the shaft for the 3pt raise/lower is moving. Sorry about the poor pic. The shaft goes under the front of the fuel tank to the valve block. My GC2300's 3pt lever has a connecting sleeve held on by a pin with a clip. Yours is probably different, but check for free movement with the engine off.
