50/48X Whole Tree Drum Chipper

The Morbark 50/48 has long been the industry standard for high-production mobile fuel and micro-chip applications, and now it’s become even better! The 50/48X whole tree wood chippers are the largest, most productive drum chippers on the market. The 50/48X was updated to a similar design layout as Morbark’s other industry-leading industrial drum chippers with a sloped infeed, reverse-pivot top feed wheel, bottom feedwheel, externally adjustable anvil and Advantage 3 drum assembly that can come as 10-knives for fuel chip or 20-knives for micro-chip applications.
