STIHL FSA 400 K Battery Clearing Saw

The STIHL FSA 400 K is the most powerful clearing saw in the ALLPRO Battery System, built for professionals who need serious cutting performance in tougher, denser growth. With power comparable to the gas-powered FS 361 C-EM, it delivers the capability to take on demanding trimming and clearing work, while its short-shaft design makes it especially well suited for working through heavy growth.

Compatibility with a wide range of cutting options means pros can tackle work in a variety of applications, giving the FSA 400 K the flexibility to adapt when the job calls for more than routine trimming. Designed to keep demanding work comfortable and controlled, the FSA 400 K features an ergonomic control handle that keeps controls within easy reach, while the STIHL anti-vibration system helps reduce operator fatigue during extended use.

Its combination of professional-grade power, a short-shaft design, and adaptable cutting options makes the FSA 400 K a capable choice for tough clearing jobs where control and maneuverability matter. Note: Tools in the STIHL AP System are compatible with both STIHL ALLPRO batteries and STIHL AP batteries.
