Product information & specifications
STIHL FSA 400 Cordless Clearing Saw
The STIHL FSA 400 is a very high-performance professional tool for heavy grass clearance, shredding dense growth and felling small trees. As STIHL's first battery-powered clearing saw, it delivers cutting performance comparable to the petrol FS 411 C-EM, with low noise and zero exhaust emissions — ideal for landscaping and grounds maintenance in noise-sensitive areas such as schools, hospitals and residential sites.
It's in stock at Gustharts as an authorised STIHL dealer. Supplied tool only, with battery and charger sold separately.
Powered by the STIHL AP System, the FSA 400 features a comfortable bike handle with quick folding clamp adjustment for a fast, tool-free ergonomic setup. A durable EC brushless motor with 3 speed levels and automatic RPM adjustment tailors performance to the cutting attachment — up to 6,900 rpm with BrushCut or PolyCut heads, around 5,000 rpm with the AutoCut head — optimising both cutting performance and battery runtime. The integrated STIHL anti-vibration system and supplied ADVANCE PLUS universal harness reduce operator fatigue on long shifts.
Key Features & Benefits
- Very high-performance cordless clearing saw for professional use
- Cutting power comparable to the STIHL FS 411 C-EM petrol clearing saw
- Ideal for tough grass, dense vegetation and felling small trees
- Low noise and zero exhaust emissions — suited to noise-sensitive areas
- Bike handle with quick folding clamp for tool-free adjustment
- 3 speed levels with automatic RPM adjustment to suit the cutting head
- STIHL anti-vibration system and ADVANCE PLUS harness for reduced fatigue
- IPX4 splashwater protection and 28mm aluminium shaft

Compatible Attachments
As standard it comes with the AutoCut 46-2 mowing head. It also accepts TrimCut 42-2, DuroCut 40-4 and PolyCut 48-2 heads, plus metal blades including GrassCut, BrushCut, ShredCut and WoodCut for more demanding clearing tasks.
Why Choose the STIHL FSA 400?
STIHL is one of the world's leading outdoor power tool brands, and the FSA 400 is STIHL's first battery-powered clearing saw to match petrol-level performance — genuinely comparable to the FS 411 C-EM, but with the quieter, emission-free operation that makes it usable in noise-sensitive sites where petrol machinery isn't welcome.
