I don't remember the depth and can't put my hands on the drawings for my
HDX-555 tower, but the contractor used a large augur then squared the
hole (sort of) by hand. He ended up using 9 yards of concrete instead of
6 1/2, but I still paid the price he quoted originally.
It didn't register at the time, but he did climb right down into the
hole, which was probably not OK, but I assumed that he knew what he was
doing, since he works with concrete all day.
