I have one of these county line augers and they work well. It cant be over emphasized about not going too deep without pulling it back out fairly often - so you dont get it buried / stuck. You wont need high RPM to do this either. My machine is pretty much at an idle when I use mine. Something else to think about is that once used for the job these augers can wind up sitting for extended amounts of time. Be sure every year to at least spray the inner shaft of the PTO - on the digger - with a good spray lube or even grease it. When these get stuck or frozen in place - getting them loose again can be hard on your religion
