This 6" capacity commercial chipper is hydraulically fed and features a distinctive 6.5 x 13 inch wide feed opening to accommodate larger brush and tree trimmings. It is powered by an electric start, 627cc Briggs & Stratton Vanguard engine for reliable starting, more horsepower, reduced fuel consumption and long life. The CH6627H also features a unique cantilever mounted rotor. This “propeller” style mounting design allows a user to chip wet or stringy wood types with less tendency of product twist or wrap. The chippers’ hydraulic feed system is electronically controlled. If the rotor speed drops below optimal operational RPM range, the controller pauses the feed roller to allow the rotor to regain speed, and then restarts feeding once optimal rotor RPM is achieved. This AutoFeed function allows for less fatigue on wear parts and maximizes efficiency. The CH6627H’s 165 lb. rotor comes equipped with four reversible, heat-treated steel chipper blades. The four-sided striking anvil is adjustable, allowing for the blades to maintain a sharper cutting edge longer and reduce repairs and blade replacement costs.
