Feel, Fuel & Noise

As the BR 430 and the BR 450 are both Stihl blowers, they benefit from the same level of quality and attention to detail.

Manufactured as backpack blowers, these two products are equipped with large engines and spacious fuel tanks, offering comfortable carrying while you work. Both products have their throttle located on the tube of the blower, which allows you to keep your left hand free.
Both products are gas-powered blowers, providing a reliable power source that can be refilled in seconds, granting you the flexibility to navigate through expansive outdoor areas effortlessly.
The Stihl BR 450, at 23.4 lbs, is only slightly heavier than the Stihl BR 430 at 22.3 lbs, so most users should experience very similar comfort and handling from both.
Though the difference in noise levels between the Stihl BR 450, rating 77 dB, and the Stihl BR 430, standing at 76 dB, may seem insignificant, it could affect both the operator's comfort and nearby residents' tranquility.

CFM & MPH

The Stihl BR 450, featuring a CFM of 695, surpasses the 500 CFM of the Stihl BR 430. With its superior airflow, the Stihl BR 450 offers an enhanced leaf blowing experience, enabling you to achieve faster and more efficient results.
With an MPH of 233, the Stihl BR 450 edges out the 219 MPH of the Stihl BR 430, potentially improving its performance in leaf blowing and debris lifting tasks.

Engine specs

With matching fuel tank capacities of 57.5 fl.oz., both devices will need refilling at comparable rates.
In comparison, the Stihl BR 430's engine displacement of 57.5 cc is slightly surpassed by the 63.3 cc of the Stihl BR 450. This indicates that the latter may consume marginally more fuel per stroke, potentially resulting in slightly greater power output. With 2-stroke engines, both leaf blowers mandate an oil/fuel mix as part of their operation.
