I had a pine tree cut down by a tree service company. The company's saw broke while cutting down the tree, and they were not able to fully cut the stump down to the ground because it was too big for the other chainsaw they had. The stump is about 3 or 4 feet tall and 3 feet wide. Any suggestions on how I can get the stump all the way down to the ground and finally removed without calling another tree service to finish the job. Also, the stump sits right on top of the water line to our house. Thanks.
