I have a Bobcat 853, the drive belt broke and has wrapped around the pully attached to the hydraulics (like 2.5 times). The belt will not budge... any ideas on how to get it off?

Burn it off. not sure if you can take a very sharp knife or something and try to cut it. it will take you a while but you will get it

Try getting a socket on the nut and turn the pumps or put bolts holes in the pulley if you cant get a socket in there. I would not try to burn it. There is a seal behind that pully and if it melts the engine and pumps need to come out to replace it. You are also on top of the fuel tank.

Can you get a chisel in there at all? see if you can cut the broken belt segment off. The only other way is to remove the pump pulley but that was be the absolute last resort! i can imagine the pain in doing it that way.
Is there any part of the belt exposed? as in enough to get a hold of it with say vice grips?
I'd be careful burning it, you don't want to damage the seal on the pump!

My son and I worked on this for the better part of a weekend, to get the belt off took a torch, a chisel, a screw driver, razor knife, and 3 foot section of both 1/8" square bar and 3" X 3/16" bar. The 1st thing I did was cut the belt where I could get to it. The problem that remained was that the belt had three sections wedged between the case and the pully. I would then heat up the 1/8" bar and burn the belt (no fire), afterward heat up the 3" bar and tap the bar with a hammer and push the belt back (out of the pully/cassing). I would use the chisel in the same fashion. This sucked to say the least, but it's done. Oh yea, I had the belt under tension with a come-along so when I finally got enough of the wraps out t pulled loose.
