Common specs comparison

Make & handling

  • Manufactured by Stihl, both the BR 450 and the BR 700 should uphold similar standards of quality and attention to detail. On both products, the throttle is situated on the blower tube, giving you the advantage of having your left hand available for other uses.
  • Manufactured as backpack blowers, these two products are equipped with large engines and spacious fuel tanks, offering comfortable carrying while you work.
  • Both products are gas-powered blowers - gas is a reliable power source which you can refill in a matter of seconds, offering you the freedom of movement to tackle larger outdoor spaces with ease.

CFM & MPH

  • The Stihl BR 700, featuring a CFM of 912, surpasses the 642 CFM of the Stihl BR 450. With its superior airflow, the Stihl BR 700 offers an enhanced leaf blowing experience, enabling you to achieve faster and more efficient results.
  • The Stihl BR 450 with an MPH of 219 slightly exceeds the 197 MPH of the Stihl BR 700, making it more effective at blowing leaves on grass or lifting wet debris (acorns, etc.).

Weight & Noise rating

  • Both products have the same weight of 23.4 lbs, ensuring a consistent level of ease when handling and maneuvering.
  • Though the difference in noise levels between the Stihl BR 450, rating 77 dB, and the Stihl BR 700, standing at 75 dB, may seem insignificant, it could affect both the operator's comfort and nearby residents' tranquility.

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 contrast, the Stihl BR 450's engine, with a displacement of 63.3cc, is slightly surpassed by the 64.8cc engine of the Stihl BR 700. As a result, the latter may consume marginally more fuel per stroke, potentially resulting in a slight power advantage.
  • 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 can vacuum leaves, so you'll need an alternative approach to collect them.
