Anyone have any experience with 12v winches, and how powerful they are, and what load they will pull? That is a 2500lb tractor, but I am pretty sure a 2500lb. wench won't budge it with the muck around it. Now, a 9000lb? I have no idea what force the mud exerts, or if a 12v (Is that what is on a tow truck) wench will even work?
