The FS 91 is built for professionals who need the performance to manage large areas, tackle long grass, and handle demanding landscape maintenance work. Its high-torque STIHL 4-MIX® engine provides the strength for tough cutting tasks, while the bike-handle design delivers the leverage and control needed to work efficiently across wider mowing areas. Practical features help keep the job moving throughout the day. One-Touch Stop and a semi-automatic choke lever simplify operation and restarting, while the solid steel drive shaft is compatible with a wide range of heavy-duty cutting attachments, including metal blades. The result is a versatile brushcutter ready for trimming and clearing applications that demand more from your equipment.
