Description
The Stihl FSA 120 is a powerful professional, battery-powered brushcutter designed for demanding grass cutting, weed clearance and landscaping work. Its efficient brushless EC motor delivers consistent cutting performance, whilst low noise emissions make it ideal for noise-sensitive areas such as schools, hospitals and residential neighbourhoods.
Powerful and Versatile – The FSA 120 features Stihl CONSTANT POWER technology, helping maintain consistent performance as the battery charge decreases. Two power settings allow you to match the machine to the task:
Level 1 – ECO mode: Ideal for lighter jobs such as edging and trimming, helping extend battery runtime.
Level 2 – Full power: Provides maximum performance for thicker grass and tougher vegetation.
The brushcutter can also automatically adjust its speed according to the cutting attachment being used.
Comfortable Working – The bike handle provides a comfortable, balanced working position, particularly when cutting larger areas of tall grass and weeds. The folding clamp makes it quick and easy to adjust the handle to suit your height.
A double shoulder harness is supplied to help distribute the weight and improve comfort during longer periods of use. The ergonomic control handle features Softgrip components for a secure, comfortable grip.
Battery Runtime – With an ALLPRO AP 200 P battery, approximate working times are:
Cutting attachment Working time: –
AutoCut C mowing head 20–40 minutes
GrassCut blade 50–80 minutes
Runtime varies depending on the cutting attachment, vegetation, conditions and power setting.
For recommended battery and charger combinations, please check the Stihl battery compatibility information before purchasing.
