Stihl FA11-011-5700 FSA50 Cordless Grass Trimmer Shell (AK)

The FSA 50 is part of STIHL's AK cordless system and delivers consistent power throughout the battery charge cycle thanks to STIHL's Constant Power technology — unlike many cordless tools where performance drops as the battery depletes, the FSA 50 maintains the same cutting power from start to finish.

The mowing head can be rotated 90° with a few simple movements, converting the trimmer into an edger without changing tools or grip. This allows clean, vertical cuts along paths and flower beds to be made in a comfortable, upright working position. The head can also be angled at multiple stages to suit the user's height and adapt to the working environment — particularly useful when trimming under low obstacles such as garden benches.

The telescopic shaft adjusts to suit different heights without tools, and the loop handle can be tilted independently to further fine-tune the working position and reduce back strain during longer sessions. The soft-grip round handle incorporates the on/off control lever and a control lever lock for safe, comfortable one-handed operation, and absorbs some of the vibration produced during use.

Speed is controlled via a variable trigger, allowing power to be dialled back for lighter work and extended battery runtime, or increased for denser vegetation — all without pausing or changing grip. A carrying ring is integrated into the body for safe, compact storage when not in use.

The FSA 50 is supplied with an AutoCut C 3-2 mowing head, which can be refilled with new line without tools. It is also compatible with the PolyCut 3-2 head (sold separately) for tackling coarser weeds and tougher vegetation. A newly designed spacer bar protects plants, bark, and surrounding objects from the cutting attachment during use — the flexible front section allows the bar to be pushed gently against objects where needed, enabling precise clearance work close to borders and beds. The bar folds up or down as required.

A spare blade can be stored directly on the tool for quick replacement in the field without needing to return to a workbench.
