Beever™ M12D Brush Chipper

With its power and easily transportable design, Morbark’s compact and economical Beever M12D brush chippers are the ideal unit for utility line clearing, residential tree services, rental yards and municipalities.

The M12D’s 18″ (45.72 cm) diameter single top feed wheel with straight flow-through infeed design easily climbs over material, reduces drag and increases chipping efficiency, allowing it to overcome the limitations of comparable disc chippers.

Chipper Disc

37″ diameter x 2″ (93.98 cm x 5.08 cm) thick chipper disc material, ultrasonically tested and certified free of material defects, has four full-length, removeable paddles for maximum chip throwing velocity.

Channel Frame

8.2 lb., 6″ Channel frame fully extends beneath the infeed for maximum support.

Infeed System

Folding infeed tray with single (top) feed wheel and straight, flowthrough infeed design for more efficient material feed.

Feed Wheel

TorqMaxTM Top Feed Wheel Compression system with spring assisted down pressure generates more than 3,200 lb./ft. (10,500 lb./m.) of material pulling force.
