This is part 2 of my project to remove a back leaning tree. This tree needed to be removed in this manner. I am pouring a cement slab right where this tree was. Using a chain saw or even digging it out would not have completely removed the roots. Not removing the roots (over time) would decay and cause the ground to sink.
