Stihl FSA 45 Straight Shaft String Trimmer

Part of the AI Series, the FSA 45 delivers STIHL quality at a value price. It features an adjustable shaft length to fit different user heights and enhance comfort. With its adjustable trimmer head, this tool can adapt to various trimming tasks. It comes standard with the STIHL PolyCut™ 2-2 mowing head, making it ideal to cut in hard-to-reach places and large areas of tall grass. Plus, you can trim the length of three football fields when its integrated battery is fully charged – that’s up to 1,080 feet. This STIHL AI Series trimmer is also just 5.1 lbs. (including battery) for easy portability and maneuverability. This trimmer is a great choice for occasional use on small properties.

Usage claim tested and verified by an independent third-party test laboratory. Run time may vary based on battery type, charge level and capacity, model, operating style and conditions. Comes with integrated battery and charger.
