Use of tire rim, tow rope and truck to remove 4x4 fence posts
Comment: breek : Needs a metal rod, a driller, a rope, a tire rim, a powerful 4x4 truck and gearbox, a good driver (otherwise parts of your car will start flying, or the post will stick in the rear of your car).
Pros: You have some fun while spending a lot of time with the setup.
Alternatives: Lever principle.
You can simply remove it as it's not cemented, by using lever-fulcrum-effort (post-ground-hands) sideways shaking couple of times. It's been used for thousands of years now. :)
