Beever™ 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 dual-sided, 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.
