I got it on ebay. It was a motor from one of those motorized shopping carts.
I'm no mechanical engineer, but this was the only thing that worked after several other methods. Tuns out that the post footings were mushroomed at the bottom. A bit over kill, but apparently that's code around these parts. I digress. . . My point is that even if it doesn't multiply the force it applied it in the right way. Plus it allowed me to use a truck to pull the posts out. :) Cheers.
