Have rented chippers on several occasions, at $100 or more a day. I would much rather have my own. Branches and trees over 2 - 3" I cut up for firewood, so I don't need a monster chipper. Anyone own one? What is minumum HP to get real work done? Is the Troybilt 10 HP Tomahawk a consideration, or is it in the catagory of homeowners' toy?
