Beever™ M18RX Brush Chipper

While retaining an 18″ (45.72 cm) chipping capacity, the Beever M18RX Brush Chipper weighs in at less than 10,000 lbs. (4,535 kg) (GVWR), eliminating the need for additional transport licensing requirements (dependent on options chosen). Infeed is made with 7-gauge (5 mm), XF-100 sides and 3/8″ (10 mm) thick, XF-100 floor to increase material tensile strength with lighter weight components.

Ideal for residential tree services, vegetation management, lot and land clearing, maintenance contractors and municipalities, this chipper combines Morbark strength in a more compact design.

Like all Morbark equipment, the M18RX is a long-lasting, durable machine backed by a world-class parts and service support team.

Morbark Beever M18RX Infeed


Oversized perimeter opening with large throat opening, radius infeed walls and straight flow through infeed design increases efficiency while reducing infeed wear.

Morbark Beever M18RX Pivot Assembly

Pivot Assembly

Bearing-style yoke pivot assembly with TorqMax™ drive and Variable Force™ down pressure system increases down pressure efficiency by 25%.

Morbark Beever M18RX Reverse Auto Feed

Reversing Auto-feed

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

Beever M20R fluid tanks

Separate Fluid Tanks

7-gauge split fuel and hydraulic reservoirs with shut-off valves reduce risks of vibration damage and cross-contamination while allowing for easy maintenance.
