The Morbark 40/36 Whole Tree Drum Chipper is a compact, affordable, productive drum chipper designed with the biomass industry in mind. Equipped with the same internal drive perfected on Morbark horizontal grinders, along with an extra wide feed opening, the 40/36 aggressively feeds brushy tops and limbs, quickly and effortlessly filling a chip van to maximum legal load capacity. Morbark’s Advantage 3 Drum decreases downtime while providing higher-quality chips. The feed system is more efficient due to a staggered knife configuration and contains fewer moving parts, reducing maintenance. With low fuel consumption per ton produced, this unit is economical. At 8’6″ (2.59 m) wide this compact unit is easily transportable and requires no permits to move.
Morbark Integrated Control Systems (MICS)
Automatically adjusts feed rates and monitors pressures and feed wheel position to maximize production and engine efficiency.
The Advantage 3™ drum creates more uniform chips, and reduces operating and maintenance costs.
Directional flow discharge chute is hydraulically adjustable by remote control for maximum chip loads.
Aggressive live floor and large top feedwheel ensure positive feed of brushy tops and limbs.
