The Husqvarna 150BT Backpack Blower delivers impressive performance and comfort for tackling everything from routine yard maintenance to heavy-duty cleanup jobs. With 22 newtons of blow force and up to 765 CFM of airflow, it easily handles heavy, wet leaves and stubborn debris. The ergonomic backpack harness system is designed for all-day comfort, helping reduce strain during extended use. An air purge system removes air from the carburetor and fuel system for quick, reliable starting, so you can get to work faster and finish the job with less effort.
