Built with a 2-stroke engine and ergonomic design, the STIHL BR 450 is a low-maintenance, high-powered blower with exceptional strength. It’s perfect for professional applications such as large property management, tough landscaping tasks, and seasonal leaf cleanup. The BR 450’s durable engine boasts reduced emissions and a blowing force approaching that of our BR 600 model. It boasts intuitive design features like a new telescopic tube and control handle which are easily adjusted without tools to enhance comfort and performance. For added convenience the BR 450 includes a built-in semi-automatic choke and simplified starting procedure, plus improved comfort elements like larger straps and backpack pads. *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.
