The STIHL FSA 400 is the first battery-powered clearing saw from STIHL. Designed for professionals working in landscaping and grounds maintenance, it has power output that is comparable to the FS 411 C-EM petrol clearing saw, and is best suited to clearing tough grass, shredding plant growth and felling small trees. The FSA 400 is battery powered – meaning it has low noise emissions, making it ideal for use in noise sensitive areas too.

The FSA 400 has a powerful EC motor and speed-adjustment on the control handle, which can be set at 3 different speed levels depending on the type of work you are doing. Automatic RPM adjustment helps with energy efficient work – the RPM increases to 6,900 when it is used with a BrushCut or PolyCut mowing head and reduces to 5,000 when used with the AutoCut head.
