looking at the danuser line.we have wet,black soil,not to many rocks.i was thinking 12" for auger.most holes will be for fence post's/planting small trees.what depth should i get 29,33,40" the model would be g20/40.thanks bws.
BWS, I would get the longest auger that they offer. All three of my augers from Bush Hog are 48"ers and I even added a 8" extension to that when I dug my holes for my pole barn (and I still had to dig further by hand). Your tractor is plenty big enough to handle the loger auger so don't bother with the shorter ones.
