hang the deer upside down, trim around the tail and hind legs, grab a handful and pull....
With a 4-wheeler or pickup truck.
Peel the hide away from the rearend, enough to put a baseball sized rock in the hide, tie a cinch knot around the rock in the hide, tie the other end to a vehicle and pull.
Just make sure the deer is tied up to something very stable, like a big tree branch. If you do this in your garage make sure you don't pull your ceiling down
