As an entry-level model, the STIHL FSA 45 battery brushcutter is ideal for trimming and clearing work in your home garden and outdoor domestic spaces. The lawn trimmer has a permanently integrated lithium-ion battery, the charge level of which can be read directly on the device by means of several LEDs.

Thanks to the fold-out spacer bracket, you can trim aroand trees and plants as well as other objects smoothly and precisely. The soft-grip handle sits comfortably in the hand and, thanks to the control lever and control lever lock, allows you to control the battery lawn trimmer reliably and safely at all times.
