When my case quit running I used my forklift to move it, just slide underneath it and put a chain around the top side just to be safe and lifted and moved it so I could get it fixed.
On my Case I need to disable the hydorstats on the transmission and it will roll just fine but different makes and models have different ways of doing things so maybe some one else will chime in.
I have one of these and in the service manual there is something about adjusting certain parts of the transmission for a manual move mode and maybe someone has done this to yours for some reason or another.
