This battery-powered trimmer combines great power and lightweight portability. 

The FSA 56 delivers STIHL performance and exceptional value. It features an adjustable shaft to fit different user heights for enhanced comfort. Its AutoCut® head feeds out new line with just a tap on the ground. And you can trim the length of five football fields on a single charge – that’s up to 0.31 miles. This STIHL AK Series battery trimmer is also just 7.3 lbs. (including AK 10 battery) for easy portability and maneuverability. And when you’re done, hang it on the wall from its onboard hanging slot.
