FSA 50 battery brushcutter: Conveniently and efficiently tackles mowing and clearing work in domestic settings
The STIHL FSA 50 battery brushcutter from the STIHL AK system impresses with its combination of powerful mowing performance, low weight and versatile adjustment options for private work in the home garden. The STIHL FSA 50 is suitable for clearing work, trimming smaller lawn areas and cutting lawn edges. In addition, the intelligent electronics make it possible for the FSA 50 to work at constantly high full power, irrespective of the charge level of the battery. Its electric motor is particularly quiet and therefore suitable for use in noise-sensitive areas. This is a great advantage, especially when working in your own garden and close to houses.
Special attention has been paid to ensuring you can work ergonomically with this battery brushcutter: The shaft length and loop handle can be conveniently adjusted without tools, and the mowing head can be angled to 3 positions. The STIHL FSA 50 can also be converted from a grass trimmer to a lawn edge trimmer in just a few simple steps, without tools. Another advantage: The fold-up and fold-down flexible spacer bar supports gentle and precise, almost flawless trimming around trees and shrubs as well as objects.
The variable speed control of the electric motor allows the speed to be continuously adjusted to the respective application. This will result in lower energy consumption and can extend the battery life. The STIHL FSA 50 is supplied as standard with the STIHL AutoCut C 3-2 line mowing head, which can be replaced without tools. This enables the mowing line to be automatically adjusted by simply tapping it on the ground, and can be conveniently filled from the outside with STIHL mowing lines without having to open the housing. Also available as an optional accessory is the STIHL PolyCut 3-2 mowing head with plastic blades, which can be changed without tools. Thanks to the practical carrying ring, you can hang the STIHL FSA 50 on the wall and store it in a space-saving manner.
