Beever™ M20R Forestry Chipper

Our versatile, high-performance M20R model built heavier in critical wear areas provides optimal performance for in-woods chipping. Easily filling a 53′ trailer and sustaining up to four to five loads per day, this hard-working, aggressive chipper is the perfect option for those looking to enter the biomass market with low startup costs.
