I bolted a winch onto a vertical post at the back of my hangar and I pull my plane IN with that. I have contemplated bolting an eyehook onto the hangar post across the taxiway on the hangars facing me and using a pulley to pull it out, but since out is downhill, I manage that one with a harness around my waste and I pull like a draft horse. Gets me some exercise. Some of the guys are using golf carts and 4 wheelers and such with towbars to pull and push their planes in and out, which of course work, some better than others.
