I used this to dig 34 holes for a friends fence she was installing. This is sold as a 1 man unit but to do it properly i'd recommend 3 guys, 1 to remove debris, and 2 to push down and keep the auger going in straight. it works good, but not for 1 person.
That Dingo looks badass and i'd recommend it for a 18" diameter hole, we were doing 8" holes and it was all that unit wanted due to clay in the soil.
