Looking at your pictures, and your woods....
I have a $50 idea for reaching in to the woods a little. If you had a good 50-60' rope (or as long as you feel like fooling with) and a rope pulley, you could tie off to a log, then put the rope through the pulley on your post hole frame and run the rope back to a close tree and tie it. Drive away until the log meets your tractor and chain it up then cut the rope loose and off you go.
I've had crazier ideas

but every foot you drive will draw the log up 2' if I'm thinking clear.
