The STIHL HSA 100 battery hedge trimmer offers effective support in horticulture and landscaping, as well as public authorities, for trimming, efficiently and conveniently in noise-sensitive areas. The STIHL HSA 100 is a very high-performance hedge trimmer with a maintenance-free EC engine, powered by lithium-ion batteries. It always delivers a constant stroke rate even under load, and even when cutting thicker branches. The double-sided cutting blade delivers precise cuts, both when trimming and pruning. If tough branches block the blade system, you can quickly get going again simply by changing the blade rotation direction.
