2004 Mitts and Merrill Chipper model k-16. The chipper is in good, well-maintained condition. It has an 84 hp cummins diesel engine with approximately 1150 hours. New tires and the drive belt was replaced within the past year. Oil and all filters were recently changed. Comes with an extra oil, air and fuel filter. It also comes with an extra set of knives that will need to be resharpened. I recently purchased a new chipper and do not need a backup. If interested make me an offer.
