Guy, I am not sure you wanted this post in the "LINKS" category???
For the purpose of exiting the hangar, assuming the aircraft is facing forward to come out, I have a tow bar that my good friend Larry gave me. It has a ball hitch in it and I can pull the plane out with my truck. This is very useful when there is snow on the ground. Using the tow bar to return the airplane to the hangar requires the hitch to be on the front of the truck. I haven't rigged my truck this way yet but would be a pretty easy task.
Using the tow bar with a ATV or lawn mower (rider) would be great as you could have the hitch on the front to pull the airplane out and return it to the hangar (that's how my friend Larry did it)
Here are some tow bars available
