DC,
Another word of caution, way back when, I once worked for a living. We regularly used power augers for digging holes for posts and plants. Yes, the handles can give you extra leverage, but, let that auger hook up on a rock and the leverage goes the opposite way as well. I had plenty of bruised ribs back in those days. Go slow, let the auger work, don't push down and do not use your body to brace the handle, if you need that much force, something is wrong down deep.
