50/48B Whole Tree Drum Chipper

The Morbark 50/48 whole tree wood chippers are the largest, most productive drum chippers on the market. Equipped with Morbark’s exclusive Advantage 3 Drum, the 50/48 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 50/48 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.

Morbark Integrated Control Systems (MICS)

This ultimate diagnostic system monitors hydraulic pressures, temperatures, clutch systems and engine efficiency to
maximize performance.
