So I've got a new 2520 on the way and I'd like to get a PHD for it really soon. My question is, has anyone tried putting an 18" auger on a 2520? I'm pretty sure it would run a 12" just fine, but I could be wrong there too.. Mostly, if its at all possible, I'd like the ability to run an 18" - but only very rarely - when putting up a couple buildings. If it won't take an 18", it won't be too bad to drill a smaller hole and hand dig it the rest of the way. Any advice?
P.S. - Any recommendations on a good brand PHD?
