I work in partnership with a friend and we clear wooded areas for landscaping, lumber and firewood. Whenever possible, we push the entire tree down with the dozer and then cut the tree as close as possible to the root ball. This maximizes the amount of wood and minimizes the amount of root balls to be burned. We then push the root balls up into a pile to dry, add oil, diesel, JP-8 if you can get it, and let her rip! If you have really large trees, you will need a really large dower. The dozer we use is around 19,000 lbs. Some trees may be too large to push over, so they will have to be cut. Either burn the stump or rent a stump grinder. When all is done, smooth out with the dozer and then landscape rake it. Just my 2 cents worth. /forums/images/graemlins/smirk.gif
