I have to set some 6 x 6 deck posts and footings close to a large maple tree. The tree is coming down so damage to it's health is not a concern. The problem is the huge roots I know I'm going to encounter. Has anyone discovered a good way of dealing with this? I'm going to go about 14" wide and 24" deep. I would rent an auger but I know hitting a root will just send me sailing off somewhere. And I don't think the tractor attached type will do anything with roots either. I thought about just going with dekbloks on top of the ground since it's going to be freestanding but I don't think I could get by with that on a 40 foot deck.
