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.

Stihl BR 450	Stihl BR 700

Higher MPH Bigger fuel tank Significantly less expensive	Higher CFM Less noisy 4-Mix engine

Feel, Fuel & Noise

Manufactured by Stihl, both the BR 450 and the BR 700 should uphold similar standards of quality and attention to detail.

Designed as backpack blowers, both products boast substantial engines and sizable fuel tanks, making them easy to carry for extended periods. On both products, the throttle is situated on the blower tube, giving you the advantage of having your left hand available for other uses.
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.
Sharing a weight of 23.4 lbs, both units provide a comparable user experience in terms of portability and maneuverability.
While the noise variation between the Stihl BR 450, recorded at 77 dB, and the Stihl BR 700, noted at 75 dB, seems marginal, it could still influence the operator and neighboring individuals.

CFM & MPH

The Stihl BR 700, boasting a CFM of 912, clearly outperforms the 695 CFM of the Stihl BR 450. With this higher CFM, the Stihl BR 700 promises a vastly improved leaf blowing capability, allowing you to tackle larger areas with ease.
The Stihl BR 450, with an MPH of 233, modestly outpaces the 197 MPH of the Stihl BR 700, ensuring slightly quicker air expulsion for more efficient leaf blowing and debris lifting.

Engine specs

With a fuel tank volume of 57.5 fl.oz., the Stihl BR 450 outshines the Stihl BR 700, which holds 47.3 fl.oz. This enables you to carry more fuel, offering the possibility of longer operation, provided the engines consume fuel at comparable rates.
When comparing engine displacements, the 64.8-cc engine of the Stihl BR 700 edges out the 63.3-cc engine of the Stihl BR 450. This indicates a potential slight increase in fuel consumption per stroke and a corresponding bump in power output. Each of these blowers requires a fuel/oil mix to operate, as the Stihl BR 450 features a 2-stroke engine, and the Stihl BR 700 is powered by the Stihl 4-Mix 4-stroke engine.
