Pulling a post can be an ordeal. I recently was asked by a neighbor to help him pull "a few posts around an old fence line" that he was having trouble with. Man, I had that manuver cold, having yanked out a bunch of old 3" round posts that had been stuck into the ground for some ancient fence line long before I bought my "country estate" (7.5 acres of scrub brush and brambles).
So, clueless per usual, I came over with my
L3410 and FEL with a few hooks welded to the upper lip, plus a chain, length of 5/8" rope, cordless drill and 4" screws (in case I needed some fixed point on the posts to cinch into). Turns out the posts were 6X6", buried 3-4' into a couple of hundred pounds of concrete. So, when I got a good grip (rope, two 4" screws) around a pole and curled the FEL, the rear wheels of my tractor lifted off the ground (yup, I had a box blade attached - thought I was fully prepared, but NOPE). That, by the way, is not a particularly good sensation (rear wheels in the air), and kind of takes the bloom off the smile on my admiring wife who had come over to watch me "help the neighbor".
So, plan B (WHY must I always resort to "plan B") involved gently nudging the the first post (there were 9, and I was already depressed) forward with the FEL, then backwards, and then repositioning the tractor and trying side-to-side. So, I nudged the post each of the 4 quadrants. It had to be modest, say moving the post 3-6 inches at the top, or I would have been likely to break the old wooden post off. It worked - I could then pull the post and cement out of the ground. Good thing, as the next option was to chainsaw the darn post at ground level, go have a beer (or 2) and lick my psychic wounds.
