Is it down yet? I don't like giving homeowners advice on things that may be dangerous. It means I am assuming your equipment is as good as mine, and you know how to use it as good as me. This could be easy. I'd take a 150', 17000 pound bull LINE and tie it a couple feet above the ground. Like Ted, I'd put several large limbs or rounds under the log to help it roll, and keep it off the ground when it comes down. Find the largest healthy tree in as straight line with the direction of pull. Put a lanyard around the base, and hook a snatch block to it, and redirect the rope out to the drive way. Some times it takes several redirects to get the rope to truck or tractor. Put the truck in 4 wheel low and slowly pull it out. I know my truck would pull it out even if the stump digs in. My Massey 135 , or JD 2010 would pull it out if it doesn't dig in too bad. They are both in the 3-4000 pound range. If it digs in both tractors would probably spin. Lighter equipment may work, but I would not try it. Good luck, and look up, that's where the danger comes from.
