Ken,
Thanks for the compliment. It is a standard sized PHD (TSC/Speeco?). I have not dug a hole yet, however knowing that clearance has been an issue, I brought the rig to my father's shop and the machinist in him took over. He's always willing to educate this son in the finer arts of metal crafting. We drilled another hole on ctr. with the others on the boom. It was closer to the lifting arms and allowed the auger bit to be 8" of the ground. I'm hoping that's enough. Take care.
Joe
