50/48B Whole Tree Drum Chipper

The Morbark 50/48B whole tree wood chippers are the largest, most productive drum chippers on the market. Equipped with Morbark’s exclusive Advantage 3 Drum, the 50/48B creates more uniform chips while keeping operating and maintenance costs low. The reverse pivot yoke produces more down pressure than the conventional style yoke for aggressive feeding of a variety of material. The 50/48B comes equipped with the Morbark Integrated Control System, allowing for both onsite and remote diagnostic monitoring of hydraulic pressures, temperatures, feed rates and more to maximize performance.
