Looks a lot like the Craftsman 77615 3-Way 250cc Gas Chipper Shredder, which you can read about on Sears web site, except mine is green. It worked great last time I used it. Trouble is I never use it anymore and its taking up space, so I'd like to give it to someone who will use it. It was about $800 new, 12 years ago.
Heavy duty wood chippershredder. Got it serviced last year. Asking 650 cash
