Feel, Fuel & Noise

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.

The Stihl BR 700, 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.
While the noise variation between the Stihl BR 430, recorded at 76 dB, and the Stihl BR 700, noted at 75 dB, seems marginal, it could still influence the operator and neighboring individuals.
