The Toro 100-9872 Snow Blower Rotor Blade ensures effective snow intake and movement through the auger system for efficient clearing. Designed as a replacement rotor blade, it mounts within the snow blower assembly to break up and direct snow toward the discharge chute. It works by rotating with the auger to gather and move snow continuously during operation. This supports consistent clearing performance, improved snow flow, reduced clogging, and reliable operation in demanding winter conditions.
