Do not buy a Morbark Chipper. I purchased a Morbark 15 Tornado in Aug of 2008, less then 2 years ago. It has been a complete lemon. The poor design and extreme vibration of the machine are literally shaking it apart. In two years, it has spent more then half of the time in the shop. It has been through 3 computers, 2 hydraulic solenoids, 3 radiators, 6 winch cables, and so many other smaller items that I can no longer keep track. They have done little to honor their warranty and even less to honor their own recalls. Save your self some money and shop elsewhere when you go looking for a wood chipper.
