Beever™ M12RX Brush Chipper

With its power and easily transportable design, the compact and economical Beever M12RX chipper is the ideal unit for utility line clearing, residential tree services, rental yards and municipalities.

The dual-sided, 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 18″ diameter single top feed wheel easily climbs over material, reduces drag and increases chipping efficiency.

Like all Morbark equipment, the M12RX is a long-lasting, durable machine backed by a world-class parts and service support team.
