I was using 6" auger for my home made post that were between 3.5 and 5" diameter. Because home made - they were not perfectly straight and had some knots. All worked smoothly. I got an electric auger for around $200 (powering it off the generator) that worked great. I was drilling at the end of wet season when soil was soft and it was taking less than a minute per hole. I dry season it takes 20 times longer with intermediate waterings of the drilled hole.
