Troy-Built CS4325 chipper shredder with Briggs & Stratton 250cc engine (approximately 8hp). Just professionally serviced, including oil change, new air filter and spark plug, carbeurator cleaning, and blades sharpened. Starts first pull. Includes tow bar for hauling around with your lawn tractor, and brand new vinyl cover to protect it from the elements if you store it outside. I don't use it enough, so selling cheap to pay some bills.
