Standard Features:

STIHL 4-MIX® engine
You can always rely on STIHL to keep setting new benchmarks this time with 4-stroke mixed lubrication technology. The STIHL 4-MIX® engine, which runs on a fuel-oil mix just like a 2-stroke, offers the benefits without the compromises of 4-stroke power. STIHL 4-MIX® engine technology provides fast acceleration, more power, added torque, lower noise, reduced emissions and increased fuel efficiency to complete jobs quickly and more easily.

Built-in sound damper
The BR 500 with built-in sound damper is built for use in noise-sensitive areas. The measured noise reduction for the human ear is up to 59% compared to the previous model** Despite the relatively low noise emission, the BR 500 is a strong, reliable helper with high performance. **Measured according to EN-ISO22868.

Anti-vibration system
Intense vibration at the handles of power tools can lead to long-term effects on blood vessels in the hands and arms. STIHL has therefore developed an effective anti-vibration system whereby the oscillations from the machine's engine are dampened which significantly reduces vibrations at the handles.

Multi-function control handle
Easy, comfortable thumb-operated control means the operator's hand never leaves the handle.

Ergonomic harness
Evenly distributes the weight between the user's shoulders, back, hips and upper thighs. With soft padding for increased comfort during prolonged use and when working on large areas.
