On my first MB, the 190Dc, soon after I bought it, I pushed in the
clutch at a RR crossing, and it didn't go out of gear. Turned out
the throwout had seized sometime before. Each time you pushed the
clutch, the throwout wore on the pressure plate arms. That day the
arms wore through, so the throwout bearing went past the arms. No
clutch. Being a torquey Diesel, after I had shut it down to stop, I
put the car in first and cranked the starter. We took off in first,
then I was able to speed match and gear jam to get into second and
then third. I got it home.
I don't suspect the tractor has this problem, but it is something to
be aware of, depending on the spring design
I think Mitch's suggestion of rust bonding may be the winning
suggestion. On the dogde caravans, the rear wheel drum brake shoed
are metallic. When it is rainy and humid, the shoes rust weld to the
drums amazingly hard. This spring after the snow all melted, After
rocking and dragging back and forth didn't break loose the rust
welds, I finally decided to "go fo' broke" (a phrase from the
Hawaiians in WWII Italian combat theater) and drag the wheels out the
driveway and hope hitting the bump across the gutter fast would break
them loose. I drug the tires squealing out the drive, across the
gutter and across the street, 75 ft or more, and only got one wheel
loose. I was really stumped, but I had to get the van out of the
street. So I put it in D (for Drag) and gunned it to drag it back
into the garage. When it bounced the gutter the second time, the
other one finally broke loose. The first time I encountered this
with the fist caravan, I took off the tire and beat on the drum with
the 10 pounder BFH until I was sure I was going to break the drum off
then take off the shoes and trash the whole thing. It finally broke
loose after a LOT of beating. Point being, that rust bonding can be
very strong.
I generally keep not so good tires on the rear so I don't ruin good
tires when this happens, and for safety, the best tires should always
be on the front axle.

I may actually be doing this relatively soon. I think I've stumbled
on to what may be an excellent deal on a small diesel tractor with
a loader and a bad clutch. Whats actually bad about it is that it
never disengages...
Bad linkage or hydraulics, or the disk is rust bonded to the
pressure plate and/or flywheel. Get it rolling and jam the loader in
the ground with the clutch pedal held down, see if the clutch breaks
loose before the tires spin.
