The SC5720B chipper/shredder/blower is powered by a 720cc Subaru EH engine. The 121 lb. rotor turns 2000 rpm at full throttle. This chipper/shredder uses four reversible chipping blades and thirty-six shredding knives to provide the most efficient method of turning branches and leaves into nutrient rich, user ready product.
ECHO Bear Cat chipper/shredders use heat-treated chipping blades and shredding knives. The thirty-six serrated edge shredding knives utilize a staggered pattern on the rotor shafts to maximize processing performance.
The SC5720B discharges processed material through a 360 degreerotational discharge tube. This truckloading feature is accomplished with integrated rotor blower paddles which "blow" the processed material through the discharge tube. Processed material size from the SC5720B is controlled by a unique screenless shredder system. The screenless system controls the amount of air flow to the housing and rotor. Less air = more time material stays in housing and is processed smaller before being discharged; More air = larger processed material and more readily discharged.
