I had driven this 800 onetime seem to run fine got it in a bind in some mud.I triedto back it out no luck.It was stuck.The motor runs fine revs up but very little movement.It feels like to me the clutch is out or a belt i have heard? Any help thank you

 

Not a HOUDINI,but would suspect you fried a belt! Also were you in low or high range? This can make a considerable difference! I have a chart at work showing 9 different ways to destroy belts and I've seen about all 9!
