Chipper Shredder Idea
Small chippers are junk. Put $100 bucks in a new engine for an old IH chipper my dad had. It's a 5hp and can barely shred thick twigs. Your better off dumping the leaves and rotating them with a pitch for or a tractor loader. Wet the pile. If you don't rotate it it won't compost. Also keep an eye on the heat. I've seen compost piles catch fire.
