The STIHL FC 91 professional edger delivers performance, long run times and rugged durability. It features a vertical pleated air filter for better filtration and STIHL-exclusive IntelliCarb™ technology for maximum RPM when air filter begins to clog. Its large 710 cc fuel tank means more work between fill-ups and its low-emission engine sips fuel to extend your run time even further. It also features a simplified starting procedure, an "open" deflector to minimize clogging and an adjustable depth wheel to ensure a consistent cutting depth.
