The cheap and dirty way to get good advice for this is to call a big tree company and have them come out to give you an estimate for removing the tree. Ask lots of questions about how they would drop it.I have a tree that needs to com down. One direction is the house, another direction is the septic tank, another is a mound system, and the last direction is more trees. Can I drop the tree on the mound system or the drainge field?
