Stihl BR 700 vs BR 450 - The differences

Further down the page, you'll find some explanations regarding the key similarities and differences between the Stihl BR 450 and the Stihl BR 700.

But before checking out these explanations, here's a table that summarizes the main pros of each of these 2 leaf blowers:

Stihl BR 450Stihl BR 700

  • Higher CFM
  • Less noisy
  • Higher cc
  • 4-Mix engine
According to Stihl's Internet Sales Policy, it is not possible to buy a NEW Stihl product online in the USA. If you're looking at getting a high quality backpack blower that can be purchased new, online, and delivered to your door, we suggest you have a look at the reliable Husqvarna backpack blowers. You may otherwise be able to find refurbished or good second hand Stihl products on eBay with the links above.

Common specs comparison

Make & handling

  • As the BR 450 and the BR 700 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 700, providing a CFM of 912, outmatches the 642 CFM of the Stihl BR 450. Your leaf blowing experience will therefore be outstandingly improved with the Stihl BR 700, as it should be able to move considerably more leaves per minute.
  • The Stihl BR 450 with an MPH of 219 slightly exceeds the 197 MPH of the Stihl BR 700. 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

  • Both devices weigh 23.4 lbs. Thus, they will be similarly tough for you to operate.
  • The noise rating of the Stihl BR 450, which is 77 dB, slightly exceeds the 75 dB of the Stihl BR 700. 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 700. 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 700. 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 700 is powered by the Stihl 4-Mix 4-stroke engine.

Other features comparison

Vacuum ability

Neither the Stihl BR 450 nor the Stihl BR 700 has the ability to vacuum leaves. Thus, you will require another method of leaf collection.
