Get great value with the STIHL FSA 57 Lithium-Ion trimmer. A lightweight, battery-powered trimmer, is an ideal choice for maintaining suburban yards.

With an AK 10 battery, the trimmer weighs just 7.5 pounds and has a run time of up to 20 minutes on a single charge. For comfort and convenience, this unit features an adjustable shaft to customize the height to the user, an easy-to-use AutoCut head that feeds a noise-reducing line and a bump guard to help the user trim carefully around obstacles like trees and shrubs. The FSA 57 trimmer is available as a stand-alone unit or as a value-priced bundle with the AK 10 battery and AL 101 battery charger.
