Common specs comparison

Make & handling

  • Manufactured by Stihl, both the BR 450 and the BR 600 should uphold similar standards of quality 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.
  • 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

  • While the difference is slight, the Stihl BR 600's CFM rating of 677 marginally outpaces the 642 CFM of the Stihl BR 450, potentially resulting in a subtle improvement in leaf-clearing performance.
  • With an MPH of 238, the Stihl BR 600 edges out the 219 MPH of the Stihl BR 450, potentially improving its performance in leaf blowing and debris lifting tasks.

Weight & Noise rating

  • At 23.4 lbs, the Stihl BR 450 just slightly outweighs the 21.6 lbs of the Stihl BR 600, potentially offering a touch more comfort in handling.
  • Although the difference in noise rating between the Stihl BR 450, registering at 77 dB, and the Stihl BR 600, at 75 dB, appears minor, it can impact both the operator's experience and nearby neighbors.

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.
  • When comparing engine displacements, the 64.8cc engine of the Stihl BR 600 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 600 is powered by the Stihl 4-Mix 4-stroke engine.

Other features comparison

Vacuum ability

Both the Stihl BR 450 and the Stihl BR 600 lack leaf vacuuming features, meaning you'll need to employ another method for leaf collection.
