Beever™ M20R Brush Chipper

The Beever M20R Brush Chipper is ideal for entry-level biomass production, lot and land clearing contractors, contractors and large tree services, this high-capacity, high-production chipper has more standard features than any other chipper in its class and is offered in a variety of configurations for incredible versatility.

For even more efficiency, select the two-speed, steel track undercarriage with 3.4 psi ground pressure and take the chipper to the material. Or add the optional 5′ (1.5 m) infeed deck for no-hassle feeding.

The 36″ diameter x 29 1/8″ (91.44 cm x 73.97 cm) wide, six-knife staggered-pocket cutting system with patented  removable knife holders increases chipping capacity.

Beever M20R Track Pivot Ass

Pivot Assembly

Bearing-style pivot assembly contours the radius of the drum, increases down pressure efficiency and reduces feed wheel dead space.

Beever M20R Forestry Auto Fe

Reversing Auto-Feed

The reversing auto-feed system with Auto Sense™ controller briefly backs material away from the drum for reduced wear and 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.

Beever M20R with Loader Overview

Ideal for entry-level biomass production, lot and land-clearing contractors and large tree services, this configuration adds a powerful Mor-Lift Model 150M hydraulic knuckleboom loader to our versatile M20R.

It’s like having three chippers in one when equipped with an optional wireless remote control. Using the loader eliminates the need for additional auxiliary equipment to feed the chipper. When the loader is cradled, the machine can be hand-fed, or fed by an auxiliary piece of equipment (not applicable when ordered with Infeed Deck) with the flip of a switch.


The Model 649, continuous rotation by-pass grapple with 6″ (15.24 cm) closed tine diameter, 49″ (124.46 cm) tine opening and 3″ (7.62) welded cylinder picks up a variety of materials.
