Thanks for all the feedback - much appreciated. I grew up in a construction company so my standard answer for all the points about bobcats, forklifts, buckets, front end loaders, et al is "I used to have that..."
but now I'm 200 miles away from all of those fun toys.
So, for now, it will just stay parked where it is.

Power Mover Inc looks like the idea I've been thinking about, sort of - but I'm picturing a tripod setup on a 3 castor base with either a pipe section welded at the top to capture the pin, or maybe a full pipe from king pin to base and still use a tripod leg setup. I have a spare aircraft power mover setup that should be able to push my unit around on the flat concrete enough to turn and park it.
