The STIHL FSA 57 delivers lightweight, cordless convenience for trimming smaller lawns and maintaining crisp lawn edges. Powered by a compatible STIHL AK System battery, the FSA 57 features an 11-inch cutting swath to help you work efficiently, while its lightweight design allows for easy maneuverability around your property.
Designed with comfort and convenience in mind, the FSA 57 features an adjustable shaft that can be customized to fit your height and preferred working position. STIHL's Instant Start technology makes operation simple. Just unlock the retaining latch and pull the trigger to get started. The TapAction™ AutoCut® cutting head allows for quick and easy line advancement with a simple tap, while the bump guard helps protect trees, shrubs, and other landscape features during trimming.
