With their rigid structural frame and powerful internal-drive, single-feed-wheel infeed system, Morbark chippers are the best you can get. They can chip small, unmerchantable material, giving you access to more markets – and higher profits. These are just some of the reasons that Morbark is the largest and most respected name in chipping.
