- Model M18R - Brush Chipper



The Beever M18R Brush Chipper boasts a huge list of options to customize the machine as well as more standard features than any other chipper in its class. The unit can be outfitted with a four- or six-cylinder diesel engine and choice of single axle, tandem axle or single axle dual wheel package. With its large capacity and high-production volume reduction capabilities, the Beever M18R Brush Chipper is perfect for residential tree services, vegetation management, lot and land clearing, maintenance contractors and municipalities. The 36″ diameter chambered air impeller system with controllable air flow vents increases chip throwing velocity and easy discharge of light, leafy material. Like all Morbark equipment, the M18R is a long-lasting, durable machine backed by a world-class parts and service support team.


TorqMax Feed Wheel

The TorqMax dual feed wheel compression system provides more than 7,500 lb./ft. of material pulling force.



The 65″ wide x 40 9/16″ high infeed chute with 31″ wide x 18″ high throat opening allows for easy feeding of a variety of materials and reduces saw labor.


Reversing Auto-feed

The reversing auto-feed system automatically stops forward feed and briefly backs material away from the drum for optimum engine performance while chipping.


Hydraulic Down Pressure

The Variable Force Hydraulic Down Pressure System eliminates the use of springs and creates 700 lbs. of perpetual down pressure.
