jurkie start

have a new commander,went out the other day , got stuck, not bad, more hung up then stuck deep but had to use the winch to get unstuck, smoked the belt a little bit trying to get out before i used the winch, problem is now when i start out slow going in forward or reverse it seems to be more jurkie than normel, friend said it may be a worn spot on the belt now that makes it jurkie now, anyone else know
