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 big 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, offering you the freedom of movement to tackle larger outdoor spaces with ease.

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.
  • With an MPH of 219, the Stihl BR 450 edges out the 197 MPH of the Stihl BR 700, potentially improving its performance in leaf blowing and debris lifting tasks.

Weight & Noise rating

  • Sharing a weight of 23.4 lbs, both units provide a comparable user experience in terms of portability and maneuverability.
  • The slight disparity in noise rating between the Stihl BR 450 at 77 dB and the Stihl BR 700 at 75 dB could have tangible effects. While the operator might experience slightly more noise, nearby neighbors may also perceive a subtle increase in disturbance.

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 700. As a result, you have the advantage of storing more fuel, potentially extending runtime, assuming similar fuel consumption rates for their engines.
  • 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.
