Common specs comparison

Make & handling

  • Belonging to the line of Stihl blowers, both the BR 450 and the BR 500 should have a shared standard of manufacturing and attention to detail. You'll find the throttle positioned on the tube of both products, ensuring that your left hand remains unoccupied for other activities.
  • These two products are constructed as backpack blowers, allowing you to comfortably carry their big engines and massive fuel tanks.
  • Both products, gas blowers, offer a swift refill system, saving you time on refueling and allowing you to efficiently manage large outdoor spaces.

CFM & MPH

  • When compared, the Stihl BR 450 demonstrates a CFM of 642, surpassing the 544 CFM of the Stihl BR 500, establishing it as the more powerful tool for swiftly clearing leaves from your yard.
  • The Stihl BR 450 with an MPH of 219 slightly exceeds the 207 MPH of the Stihl BR 500. Thus, in comparison, the former expels air at a slightly higher speed, and should do a better job at blowing leaves on grass or lifting wet leaves and debris (acorns, etc.).

Weight & Noise rating

  • The Stihl BR 450, weighing 23.4 lbs, edges slightly above the 22.3 lbs of the Stihl BR 500, implying that while it's marginally heavier, you may notice a tad more comfort and ease in handling the latter.
  • At 77 dB, the Stihl BR 450 produces a substantially louder noise compared to the 65 dB of the Stihl BR 500. This means that the latter will provide a significantly quieter operation, ensuring greater comfort for you and minimizing noise impact on those around you.

Engine specs comparison

  • The Stihl BR 450 boasts a larger fuel tank capacity, with 57.5 fl.oz., surpassing the 47.3 fl.oz. of the Stihl BR 500. Consequently, you can store more fuel, potentially extending operational time, assuming similar engine fuel consumption rates.
  • When comparing engine displacements, the 64.8cc engine of the Stihl BR 500 edges out the 63.3cc engine of the Stihl BR 450. This indicates a potential slight increase in fuel consumption per stroke and a corresponding bump in power output.
  • Each of these blowers requires a fuel/oil mix to operate, as the Stihl BR 450 features a 2-cycle engine, and the Stihl BR 500 is powered by the Stihl 4-Mix 4-stroke engine.

Other features comparison

Vacuum ability

Neither the Stihl BR 450 nor the Stihl BR 500 can vacuum leaves, so you'll need an alternative approach to collect them.
