30/36 Whole Tree Drum Chipper

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.
