Toro Power Max two stage Snow Thrower Auger System: A breakthrough in snowthrowing technology, the Power Max® auger system handles more snow in less time without bogging down to get the job done fast! This revolutionary system meters snow intake to reduce clogging. Snow not immdediately thrown is returned back into the auger, providing maximum impeller speed and snowthrowing velocity. The expanded chute base with its inverted, funnel shaped design has a larger opening and a non-stick surface to minimize snow build up.
