Who would have thought a backpack blower as powerful as the professional BR 500 would also be quiet? With a proven low emissions engine, this gas leaf blower has all the features you need to work all day, everyday. Designed with a simplified starting procedure for single-handed operation, it has the quality you’d expect from a STIHL backpack leaf blower: a comfortable weight, reduced vibration levels and a low starting force. *A majority of STIHL gasoline-powered units sold in the United States are built in the United States from domestic and foreign parts and components.
