I appreciate the size of the stump but really with a machine that big and expensive i would have thought it would eat through it a bit quicker than that

two or three and you have to replace the cutting tools. simply burn it. also saves fuel and work time.

4 minutes, too long unless that is your only option or your only stump. Tub grinders love stumps

Comments ... Does anyone know how this compares to the Prime Tech going head to head????

Would it be more efficient to pick up the stump and put it inside a machine designed to chip it or haul it away? The mulcher is designed for clearing smaller trees. It can mulch it, but the stump is too big for the 800 model.

It may be easier to just pick the stump up in a stump pile and stick a match to them. I agree that it's a slow process and uses up a lot of diesel fuel and time.

Mulching this material back into the ground is sustainable practice. the problem is everyone wants to just burn everything. It may take some time but it is better for the forest The ground will benefit greatly from this material getting mixed back in. No I'm not a hippie I work building logging roads, and also operate on the logging side of things. We have done nothing, but take from the forest in most places  we never give anything back. This may take more time and go through a lot of diesel but it is good stewardship practice for the forest. And that is what is important. People only think of there bottom line instead of good forestry practice
