It all depends upon your need whether a stump is to be removed or grinded. In removal process, stump is removed digging the ground and removing roots underneath. On the other hand stump grinding s done just to level the ground. Stump is usually removed if you want to plant another tree or vegetation on that land. If you just want to make a driveway over that land, then it is a better idea just to grind the stump to level the ground and use that land. We do it all.
