Designed for landscape professionals and demanding homeowners, the STIHL FSA 120 battery brushcutter delivers powerful performance with exceptional efficiency and comfort. Ideal for maintaining large green spaces, it operates quietly enough to use without hearing protection—making it well suited for noise‑sensitive environments such as schools, hospitals, and city parks.
The high‑performance EC motor features two adjustable speed settings controlled directly from the handle. ECO mode (level 1) reduces energy consumption to extend battery life during lighter tasks, while level 2 provides maximum power for tackling dense grass and scrub. The variable speed control allows you to match performance precisely to the task at hand.
An ergonomic bike handle ensures comfortable, efficient operation across wide areas. The FSA 120 is compatible with a broad selection of cutting tools and mowing heads, giving you flexibility for a wide range of applications.

Constant Power
CONSTANT POWER, REGARDLESS OF BATTERY CHARGE STATUS. With other brands of battery tools, the performance usually decreases during work as the battery discharges. This is not the case with STIHL cordless power tools with CONSTANT POWER. Thanks to the intelligent electronics, your STIHL power tool works with consistently high power.
Power Levels
PERFORMANCE SUITABLE FOR THE TASK. You can change the power of your device thanks to 2 different power levels. At level 1, you reduce the power (Eco mode) and extend the battery life. Level 2 allows you to call up full power. This means that you can either work particularly energy-efficiently or use all the power of the device when you need it.
Ergonomic Bike Handle
EFFORTLESS MOWING OF LARGE AREAS. The ergonomic bike handle helps you mow large areas quickly and effortlessly, as this handle supports a natural brushcutter movement. The bike handle is easy to adjust and secure.
Tool-Free Handle Adjustment
SET THE BIKE HANDLE POSITION. You can individually adjust the ergonomic bike handle (mowing handle) using the central clamping device. Thanks to the tool-free handle adjustment, you do not need any tools for this. The bike handle can be rotated 90 degrees for transport and space-saving storage.
