Common specs comparison

Make & handling

• As the BR 450 and the BR 500 are both Stihl blowers, they benefit from the same level of quality and attention to detail. Both products have their throttle located on the tube of the blower, which allows you to keep your left hand free.
• These two products are constructed as backpack blowers, allowing you to comfortably carry their powerful engines and massive fuel tanks.
• Both products are gas-powered blowers - gas is a reliable power source which you can refill in a matter of seconds.

CFM & MPH

• In comparison, the Stihl BR 450, with a CFM of 642, beats the 544 CFM of the Stihl BR 500, making it the superior landscaping tool of the two, when it comes to the amount of leaves that can be blown per minute.
• 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 weight of the Stihl BR 450, which is 23.4 lbs, slightly exceeds the 22.3 lbs of the Stihl BR 500, and will therefore require you to carry around slightly more weight.
• The Stihl BR 450 produces 77 dB, which is significantly higher than the 65 dB of the Stihl BR 500. Thus, the latter will be much easier on your ears.

Engine specs comparison

• The Stihl BR 450's fuel tank has a volume of 57.5 fl.oz., exceeding the 47.3 fl.oz. of the Stihl BR 500. Therefore, you may store more fuel in the device and theoretically operate it longer, if their engines are equally demanding.
• In comparison, the Stihl BR 450's engine displacement of 63.3cc is slightly outperformed by the 64.8cc of the Stihl BR 500. This suggests that the latter consumes slightly larger amounts of fuel per stroke and will provide you with slightly more power.
• 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 has the ability to vacuum leaves. Thus, you will require another method of leaf collection.
