That is what I was wondering. On paper they seem pretty good as well as in some videos I have been watching. I would have thought it would have plenty of power too.My first and only experience with one was a few months ago augering post holes. It was a Dingo with an 18" bit. Tracked. It did what we needed it to do with no issues.
I wouldn't look at it as a machine for high production.. Only something for menial specific tasks like digging post holes or entering restricted space areas. The one I used did not have enough ass to pull a loaded auger but out of the ground. The hydraulics were there, just not enough weight.
