If you’ve got something strong and substantial to hang your deer from, you can pull the skin off with a jeep or four wheeler by tying a rope and gently reversing away from deer. You’ve got to have a strong enough support that there isn’t much give and as already mentioned, it always easier if deer isn’t cold.
First, with deer hanging from strong support - cut the skin around the neck and pull down enough to put a rock behind the skin - something big enough to get a rope behind/around and tied off. Tie the other rope end to the bumper of truck, jeep, four wheeler and reverse slowly and ease away from deer carcass with deer pulling away at roughly 45 degree angle. If you’ve got a buddy there, have him help the skin off with a skinning knife as the hide is peeling off (again, slow and easy).
The above probably sounds complicated and possibly unsafe but if done gently, you can have a deer skinned in a few minutes with virtually no effort. I’ve skinned dozens upon dozens of deer this way over the years with no mishaps aside from knot coming loose from the deer that required repeating the process.
Slow and easy like a Don Williams song…
