Further down the page, you'll find some explanations regarding the key similarities and differences between the Stihl BR 450 and the Stihl BR 600.

  • 4-Mix engine

Common specs comparison

Make & handling

  • As the BR 450 and the BR 600 are both Stihl blowers, they benefit from the same level of quality and attention to detail. The throttle for both products is conveniently placed on the blower's tube, freeing up your left hand for other tasks.
  • These two products are constructed as backpack blowers, allowing you to comfortably carry their big engines and massive fuel tanks.
  • gas-powered blowers, both products offer a dependable power source that can be refilled quickly, allowing you the mobility to cover extensive outdoor spaces without interruption.

CFM & MPH

  • With a marginal CFM advantage (677 vs 642 CFM), the Stihl BR 600 may offer a modest edge over the Stihl BR 450 (642 CFM) in terms of leaf-moving capability.
  • The Stihl BR 600 with an MPH of 238 slightly exceeds the 219 MPH of the Stihl BR 450, making it more effective at blowing leaves on grass or lifting wet debris (acorns, etc.).

Weight & Noise rating

  • The weight of the Stihl BR 450, at 23.4 lbs, slightly exceeds that of the 21.6 lbs Stihl BR 600, which means you may experience slightly less fatigue and find it easier to maneuver during prolonged use.
  • The slight disparity in noise rating between the Stihl BR 450 at 77 dB and the Stihl BR 600 at 75 dB could have tangible effects. While the operator might experience slightly more noise, nearby neighbors may also perceive a subtle increase in disturbance.

Engine specs comparison

  • The Stihl BR 450 features a larger fuel tank, offering 57.5 fl.oz. compared to the 47.3 fl.oz. of the Stihl BR 600. As a result, you have the advantage of storing more fuel, potentially extending runtime, assuming similar fuel consumption rates for their engines.
  • In comparison, the Stihl BR 450's engine displacement of 63.3cc is slightly surpassed by the 64.8cc of the Stihl BR 600. This indicates that the latter may consume marginally more fuel per stroke, potentially resulting in slightly greater 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 600 is powered by the Stihl 4-Mix 4-stroke engine.

Other features comparison

Vacuum ability

With no leaf vacuuming functionality in either the Stihl BR 450 or the Stihl BR 600, you'll have to find another way to gather leaves.
