I know you've all ready pulled it out, but a technique that would be good for future use is to make a stump arch. I can't seem to find pictures or anything online, though that's where I learned about it. Basically, you make a large lever to convert the forward force of the truck to a mostly vertical force that is much more powerful. I made mine with 2 4x4x6 posts attached at the top to make a triangle and braced at the bottom to keep them from pulling apart under load. Then I suspended a chain grab hook from the point. To pull a stump I wrap a logging chain around it, then set up the arch over it so that it is sort of leaning back over the stump, then I run the chain through the grab hook and connect to a tow strap that I attach to the hitch on my truck. With 4-lo I slowly take up the slack and ease the stump out of the ground. This allows me to pull huge stumps with minimal strain on my truck and no damage to lawns from wheel slip. This is a similar idea to using a tire rim, but more powerful. For every foot that the truck goes forward, the stump is only pulled up a couple of inches, which is a significant mechanical advantage, and by the time the arch tips over forward and its just a straight pull, the stump is pretty much up and out of the ground. The key is the grab hook which doesn't allow the chain to slip, making the arch a lever instead of just a pulley.
