MORBARK 30/36 Whole Tree Drum Chipper

Drum Chippers

The Morbark 30/36 Whole Tree Drum Chipper’s high production rate lowers operating costs by increasing fuel efficiency. The aggressive live floor feeding system with two strands of durable WHD-120 chain and a large top and bottom feedwheels ensure positive feeding of material, including brushy tops and limbs. Morbark’s Advantage 3 Drum produces more consistent chips, while the heat-treated, AR-400 steel drum skin provides longer wear life for lower replacement costs and less downtime.

  • Optional Forestry Grate - The operator-friendly, slide-in forestry grate system reduces oversized chips for more consistent, higher-quality chips.
  • Sloped Infeed System - Aggressive, sloped live floor and large top and bottom feedwheels ensure positive feed of brushy tops and limbs.
  • Discharge - Directional flow discharge chute is hydraulically adjustable by remote control for maximum chip loads.
  • Optional Chip Accelerator - A mechanically driven chip accelerator fully loads vans with chips.
  • Morbark Integrated Control Systems (MICS) - This ultimate diagnostic system monitors hydraulic pressures, temperatures, clutch systems and engine efficiency to maximize performance.
  • Drum - The Advantage 3™ drum creates more uniform chips and reduces operating and maintenance costs.
