HG rear sprockets stuck

[outbackrider]

One of my HG's has a rusted/stuck transmission shifter and is stuck in
first gear.  Back in March, I removed the "dog bone" shaft between the clutch
and transmission, I pulled the machine about 100 feet with my backhoe and the sprockets and
tracks turned without issue. Today, I wanted to move the machine closer to the
house so I could start to dismantle the finals and pull the transmission.   The sprockets
won't turn, I tried pushing, pulling, dragging a bit and it is still locked
up.  Scratching my head on why in March, it pulled fine, and today, a fair weather
day and I can't get it to move.   

Any thoughts?  I'd just like to get it closer to start working on it.

Thanks.

Is the shifter still stuck? Could someone have played on it and somehow got it into two gears?

Thanks Blake. Yeah the shifter are still stuck on the rails..The shifter shaft pulls right out and I can see that
it is not in two gears, this is crazy, I should have just pulled it up to the work site when it moved, but
I needed to have someone steer it.  My son was away at college and he just came home for the weekend.
Figured it would be an easy move..I still can't believe that it rolled and now is locked up.  I
just can't figure the issue.
Tracks are rusted but are free.  I don't want to try to disassemble in the area that it is in.

Could the clutch be stuck and the engine too? That happens.
To free it, you usually have to start it in whichever gear it is in and slam it into something or brake hard or change gear on the fly - something to 'shock it' loose.
Just an idea, other than ice which hopefully you are passed getting...a flake or three of snow due here tomorrow! Grrrrr

Thanks Chris, back in March I disconnected the universal drive (dog bone) drive shaft, as
the engine is presently stuck...so the tranny is not making any connection with the clutch/engine.

Other than a really large front loader...have you come up with any good ways to move
these units?

As far as weather...it's been warm so no ice in the differential.

Now we're into some serious guessing. Roller bearing part or tooth chunk fell out and jammed between the final drive gears? Do both sprockets appear to be jammed?
Bummer.
I guess with a bit of messing with making a strong hitch you could skid it out on a sheet of 3/4in. plywood, depending on the ground you have? Or take the tracks off and drag it. That way only the sprocket teeth will be digging in and the idlers/rollers will take some of that weight. Or drag it backwards to lift the sprockets out of the dirt a ways?
Or like you say, good loader or big rough terrain forklift. Best of luck.

If you don't have a PTO you can probably have the back cover off in 15 minutes. A bit longer with a PTO.

I have an early ROPS on this machine, so accessing the differential cover is not easy.
I plan to remove the ROPS and plan to reconfigure the mounting design.  I'll then
check to see what's going on in there...Seems I might be pulling it apart where it sits..
