For comfort and convenience, this unit features an adjustable shaft to customize height to the user, an easy-to-use AutoCut® head which feeds 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. Other battery options are available.
