Well. Not sure why no one has posted this idea yet, but this is how i do it. I beleive mr. quad guy is just kidding around. but first cut the skin all the way around the neck then down the chest to right above his testicles. cut slits up each leg and then stop just past the joint. cut a circle around the joint. lay him out on a tarp and put a chain around his neck and around the base of a sturdy tree. pull back the skin around the neck and place a medium rock in there and use rope to tie a good not around the rock then conect the other end to a vehicle. start to pull SLOWLY and watch the skin come right off. don't matter if it is hot or freezing cold.
