The STIHL FSA 80 R is a powerful battery-powered brushcutter designed for demanding mowing, trimming, and clearing tasks in home gardens. As part of the STIHL AK System, this model delivers high cutting performance with low noise emissions, making it ideal for residential use without disturbing neighbours.
 
Fitted with a loop handle, the FSA 80 R offers excellent control and manoeuvrability in tight or narrow areas, such as between shrubs, along fences, or around park furniture. The handle can be adjusted quickly and without tools for a more ergonomic working position, and an integrated eyelet provides safe and compact storage.
 
At its core is a durable brushless EC motor, delivering consistent performance across the entire battery charge, with no reduction in cutting power as the battery runs down. Additionally, regenerative braking technology recovers energy when the throttle is released and feeds it back into the battery, helping to extend runtime.
 
The control handle features three-stage speed adjustment with a built-in LED display, giving you real-time feedback on power settings. You can also switch between:
Eco mode (Level 1) – ideal for light trimming and maximum battery life.
Full speed mode (Level 2) – for tougher grass and denser vegetation.
 
The FSA 80 R is supplied as standard with the GrassCut 230-2 metal blade and a basic shoulder harness. It is also compatible with a range of optional STIHL cutting attachments, including:
AutoCut
TrimCut
DuroCut
PolyCut
 
These cutting heads are mounted using standard tools, not via a click system, offering flexible options depending on the vegetation being managed.
With the recommended AK 20 battery, the FSA 80 R delivers up to 25 minutes of working time. If purchased as part of a set, it includes the AK 20 battery and AL 101 charger. The balanced battery position also enhances the handling and overall comfort of the tool during use.
