Thought this might be interesting to other members that need a way to easily pull fence posts or the like.
I did something similar to his photo, (below), years ago. I sawed the posts off, flush with the ground, ran a big lag bolt into the top. Placed a large piece of wood, about 2" thick, with a hole in the center. Put a chain, with a 2 fingered hook, through the hole, onto the bolt head. And pulled them out, with an old bumper jack.
