I have nothing negative to say about the BH 92, other than delaying getting it for 7 years, due to the price. Actually, I believe I started out not being able to afford the BH-90 until that model was replaced. I've used it to remove our old, unused septic collection & distribution tanks. Dug out about a dozen stumps, then burried them when I found out my town wouldn't issue a burn permit. No thumb, but I see the utility and want one. One bucket -18" - seems to be a good general purpose size.
