FINALLY THE CONCRETE IS GONE!
I hired a local guy in town to get rid of the concrete, he brought a dump truck, skid steer, pallet forks, bucket and a hammer. It wasn't a jackhammer (although he has one) but it was a hammer of a sort, he would roll back the hammer so it would bounce and while the hammer went up then he would drop the loader and hit the concrete with a lot of force. After hitting the big piece of concrete for about 3 minutes, he then put the forks on and picked up on one side of the concrete. The concrete then fell into two pieces, he used the hammer again to break loose the rebar holding the two pieces together, then he was able to lift each half into his truck.
It took him a hour to get it all loaded and his truck was full when he was done. He also pushed up the metal junk and then he pushed up a small brush pile.
It only cost me $160 and he hauled off the concrete, I thought it was a fairly good deal. Since my other option was a sledge hammer.
