The Morbark Beever M12R brush chipper features design and productivity improvements. Key modifications to the Beever M12R include a reduced overall size, widened infeed, separated fuel and hydraulic tanks and the incorporation of a chambered air impeller. Shortening the machine length by 15 inches makes it easier to park and maneuver. The increased infeed width results in a 25-percent greater infeed perimeter opening making the feeding of branchy material less difficult. Separate fuel and hydraulic tanks eliminate the chance of cross contamination between fuel and hydraulic oil; and a separate fan chamber increases air flow with less “blow back” at the operator.
