STIHL BR 450 Backpack Blower

The BR 450 is a high performance machine that produces plenty of blowing power for those tougher jobs. With a toolless, fully adjustable blower tube and control handle, the BR 450 offers optimized ergonomics for prolonged use. Perfect for removing grass and hedge clippings, leaves or rubbish. Features: Anti-vibration system: Intense vibration at the handles of power tools can lead to long-term effects on blood vessels in the hands and arms. STIHL has therefore developed an effective anti-vibration system whereby the oscillations from the machine's engine are dampened which significantly reduces vibrations at the handles. Multi-function control handle: Easy, comfortable thumb-operated control means the operator's hand never leaves the handle. Ergonomic harness: Evenly distributes the weight between the user's shoulders, back, hips and upper thighs. With soft padding for increased comfort during prolonged use and when working on large areas. Blower tube with adjustable length: The blower tube can be fully adjusted to the size of the user or to suit the job STIHL ElastoStart: STIHL ElastoStart reduces the shock caused by the compression of the engine during starting. The compression shock is taken away from the user's joints and muscles through a spring or rubber element in the starter handle.   Technical data Value Sound pressure level (dB(A)) 77 Displacement (cc) 63.3 Engine Power (kW / bhp) 2.9 / 3.9 Blowing Force (Newtons) 1) 28 Average Air Velocity (m/sec) / (mph) 2) 83 / 186 Maximum Air Velocity (m/sec) / (mph) 2) 98 / 219 Air Volume at Nozzle (m3/h) / (cfm) 2) 1,090 / 642 Weight (kg / lbs.) 10.6 / 23.4 Displacement (cc.) 63.3 Power Output (kw / bhp.) 2.9 / 4.0
