I'm digging a 36" deep post hole for a fence I'm putting up, and about 15" down I ran into a very large root. Since the root seems to be running almost directly in line with the fence, and there isn't a tree attached to said root, I'd like to get rid of the root.
I've been using a reciprocating saw to cut out hunks of it, but this has been very tedious and not as effective as I would like. Is there a better way to get rid of the root? It appears to be around 9" in diameter
