Thread: Post hole borer recommendations

I've finally decided to get a post hole borer. We have a block of land that my son will soon be building on and besides general fencing and some tree plantings, I'm thinking of building a basic shelter for our old tractor. I guess I'd need at least a 200mm auger and possibly up to a 250.

I see many of these have only a ~40cc engine and look lightly built. Those bigger two-man units are possibly more what is needed here. What a people's experiences/recommendations?
