Once it's about as light as you can get it, and if still too heavy, could you chain it and lift it or drag it out? You may have to slope one end of the hole, to kind of serve as a ramp, but that might be a heck of a lot easier than trying to use that bucket to pick it up. That sure is one big stump - /forums/images/graemlins/blush.gif makes that bucket look a little small I must say. Looks however like it did a fantastic job of breaking the roots and digging it free.
