Lumag designed the HC15 RAMBO Chipper to break down branches & sticks up to a 120mm diameter. The Chipper is powered by a 15HP single cylinder petrol engine. The engine transmits its power to the chipper drum via a centrifugal clutch & a pair of thick rubber drive belts. The HC15 features both an electric key start as well as a traditional recoil start as a backup. The chipper drum is mounted on 2 sealed bearings & features 2 opposing double-sided (reversible) hardened chipper blades, these blades rotate anti-clockwise toward the adjustable counter knife at between 3000 & 4000 RPM. The blade clearance between the chipper blades & chippers counter knife is optimal between 0.5 & 1mm. The chipper can process branches with a maximum diameter of 120mm. We have found that its optimal working range is around 80-100mm depending on the moisture level hardness & all manner of other factors affecting the wood you are chipping. The Lumag HC15 Chipper is mounted on an 800mm wide towable chassis with a 50mm ball hitch & safety chain. The chipper is fitted with large pneumatic tires making it easy to handle & maneuver to your desired chipping area. The HC15 Chipper has been designed with two useful handles integrated into the intake hopper, these are at a nice working height & allow the chipper to be tilted back to a point of balance & moved around easily by hand without a tow vehicle. The intake hopper of the chipper is also fitted with a hinge making access to the chipper drum & blades very easy. The chipper outlet chute is fitted with a 360-degree swivel head allowing the material from the chipper to be directed to where you need. The garden chippers stand leg folds up & is retained by a locking pin for transporting around. (while on tow). The Lumag HC15 Chipper is fitted with an emergency cut out switch operated by a safety bar around the chipper’s intake hopper, the chippers other safety features include a belt guard covering the chipper’s drive belts.
