The SC3265 chipper/shredder reduces yard debris, while helping operators be kind to the environment. The 3-in. chipper/shredder comes with a 265cc Subaru engine; two reversible, heat-treated steel chipper blades to reduce maintenance costs and blade replacement; 12 serrated shredding knives; 1.5-in. screen standard (three other screen options are available); and a double-banded belt drive for an equal transfer of power.
