I hang them by the legs. This is the way we butcher our beef so i have been taught this method as a little guy. I skin out the legs till just past the tendon. Then i hook a small chain on each leg in between the tendon and the bone. The i drive the tractor up and hook the chains on the forks of the loader. You have an instant hoist and good lighting if the skinning needs to be done after dark. Using the tractor is real handy for large animals such as an elk or beef. We split the animal then drive the tractor up over the truck box. One fella hops up on the truck box and grabs the front legs while the loader operator lowers the halves and backs up at the same time.
