FSA 57 Kit



The powerful mowing performance of the lightweight STIHL FSA 57 battery grass trimmer helps you effectively trim smaller lawns and lawn edges. The FSA 57 grass trimmer is powered by a STIHL AK-System battery. Its electric motor makes this power tool very quiet and therefore suitable for use in noise-sensitive environments. This is a valuable advantage, especially in home gardens and in residential areas.

This battery grass trimmer has been specially designed to enable you to work ergonomically: the shaft length can be adjusted at the push of a button. You can also adjust the loop handle without tools. The softgrip handle with control lever is extremely easy to grip and absorbs some of the generated vibrations. A spacer bracket which can be folded up or down supports precise and gentle trimming around trees and shrubs, as well as around objects. The battery-powered grass trimmer is equipped as standard with a STIHL AutoCut C 3-2 line mowing head, which can be refilled without tools.

STIHL recommends using a round, quiet mowing line for battery grass trimmer with a line mowing head. This not only reduces noise pollution as you work, but has also proven to be more efficient in tests. Compared to a round mowing line, battery life with this type is up to 10% longer with the same cutting performance. STIHL supplies battery grass trimmer with line mowing heads with a round and quiet mowing line as standard.
