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. 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

• The Stihl BR 600 with a CFM of 677 slightly exceeds the 642 CFM of the Stihl BR 450. Thus, in comparison, you may find that the former is able to move more leaves per minute.
• The Stihl BR 600 with an MPH of 238 slightly exceeds the 219 MPH of the Stihl BR 450. 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 21.6 lbs of the Stihl BR 600, and will therefore require you to carry around slightly more weight.
• The noise rating of the Stihl BR 450, which is 77 dB, slightly exceeds the 75 dB of the Stihl BR 600. Even if this difference could seem unsignificant, the former is still slightly more noisy.

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 600. 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 63.3 cc is slightly outperformed by the 64.8 cc of the Stihl BR 600. 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 600 is powered by the Stihl 4-Mix 4-stroke engine.

Other features comparison

Vacuum ability

Neither the Stihl BR 450 nor the Stihl BR 600 has the ability to vacuum leaves. Thus, you will require another method of leaf collection.
