The FSA 50 is supplied with the AutoCut C 3-2 mowing head which can be refilled without the need for tools. It can also be used with the PolyCut 3-2 too (sold separately). The grass trimmer is fitted with a soft grip round handle that can be adjusted without the need for tools. It also has a re-designed adjustable telescopic shaft and a mowing head that can be set at 3 different angles. This helps you to trim in awkward areas, such as underneath benches or when mowing along slopes, around trees or on uneven terrains. A newly designed spacer bracket protects the grass trimmer from damaging fragile objects such as plants and flowers too. Plus, the mowing head can be rotated 90 degrees for trimming along lawn edges.
A variable speed trigger allows you to precisely control the speed of the mowing head, which helps to extend the working life of your battery too. Excellent balance and a low weight make this an ideal entry-level grass trimmer for operators of all ages and abilities.
On a full charge with the AK 10 battery, the FSA 50 has a working time of up-to 25 minutes. What’s more, this battery provides perfect balance when used, making work even more comfortable!
