Feel, Fuel & Noise

Manufactured by Stihl, both the BR 350 and the BR 500 should uphold similar standards of quality and attention to detail.

These two products are constructed as backpack blowers, allowing you to comfortably carry their big engines and massive fuel tanks. 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.
The Stihl BR 500, at 22.3 lbs, is only slightly heavier than the Stihl BR 350 at 22 lbs, so most users should experience very similar comfort and handling from both.
At 74 dB, the noise rating of the Stihl BR 350 surpasses that of the Stihl BR 500, which stands at 65 dB. Therefore, choosing the Stihl BR 500 could offer a quieter environment for both you and your neighbors.

CFM & MPH

In contrast, the Stihl BR 500, with its CFM of 544, outperforms the 436 CFM of the Stihl BR 350, making it the preferred option for efficiently blowing leaves away.
The MPH of 207 for the Stihl BR 500 slightly outperforms the 201 MPH of the Stihl BR 350, enhancing its effectiveness in clearing leaves on grass or lifting wet debris.

Engine specs

The Stihl BR 350's fuel tank has a volume of 57.5 fl.oz., exceeding the 47.3 fl.oz. of the Stihl BR 500. Therefore, you may store more fuel in the device and theoretically operate it longer, if their engines are equally demanding.
When comparing engine displacements, the 64.8-cc engine of the Stihl BR 500 edges out the 63.3-cc engine of the Stihl BR 350. 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 350 features a 2-stroke engine, and the Stihl BR 500 is powered by the Stihl 4-Mix 4-stroke engine.
