Our Beever™ M15R brush chipper is ideal for residential tree services, utility line clearing, vegetation management, maintenance contractors and municipalities, this high-capacity, high-production chipper includes more standard features than any other chipper in its class. The Beever M15R 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 powerful TorqMax™ dual feed wheel compression system generates more than 6,600 lb./ft. (9,820 kg./m.) of material pulling force. Many customer-inspired innovations are featured on the M15R, increasing efficiency and safety while reducing operating and maintenance costs. Unit is pre-plumbed and outfitted for the easy installation of most aftermarket components. Ergonomic infeed design provides consistent feed control bar activation.
