Beever™ M12R Brush Chipper

Perfect for utility line clearing, residential tree services, rental yards and municipalities, this powerful and compact model is easy to maneuver. The Beever M12R Brush Chipper is also available tracked for right of way clearing, highway clean-ups and hard-to-reach areas requiring a self-propelled unit for material access.

The patented chambered air impeller system increases chip throwing velocity and reduces dust and material blowback out the infeed to pack more into the chip truck.

The direct driven dual feed wheel system with serrated teeth and knife bar combination and end cap ripper teeth allow positive material feeding and reduced material wrapping around the feed wheel shaft for increased feeding efficiency.

The M12R is available in a PTO unit for those who have access to a commercial tractor.

Like all Morbark equipment, the M12R is a long-lasting, durable machine backed by a world-class parts and service support team.
