Well it's the first time it's happened to me......I had to move it to my other place for now. The other place is about 100 miles from my house and I still had it on my trailer. I figured it would be easy to unload.....take off the straps, start it up and back it off. No such luck with the backing off part. Something is jammed up. Not sure if it's the transmission or something else. Didn't have time to mess with it last night. So when I go back for it in a couple weeks I need to take two tires and some tools to see if I can break it loose. Kinda feels like the trans is hung in two gears or something and the shifter is really stiff.
