If you’re a landscaping professional who uses their trimmer for mowing applications, grab the powerful STIHL FS 91 trimmer. Its bike-handle design adds greater comfort and leverage, thanks to its redesigned rubberized grips. The trimmer also features one touch stop and a simplified starting procedure enabled by the semi-automatic choke lever. Its low-emission engine is paired with a larger fuel tank, delivering 30 percent longer run times when compared to the FS 90. The engine also includes improved air filtration and STIHL exclusive IntelliCarb technology for maximum RPM. And when the terrain gets tough, this trimmer’s solid steel drive shaft accepts a wide range of heavy-duty cutting heads, including metal blades, for maximum versatility.

The IntelliCarb compensating carburetor measures the air pressure on the clean side of the air filter and adjusts the metering diaphragm in the carburetor

Loop handle grass trimmers and brushcutters are ideal for trimming between bushes and shrubs and other areas where space is limited

Smooth operation and less vibration

Having easy access to all of the controls on one comfortable handle makes it easy to complete tasks so the operators hand never has to leave the handle

The central wing nut enables easy adjustment without the use of tools

Housings are lightweight, withstand greater impact and are corrosion-resistant

Air filter cover is easily removed for fast and easy filter cleaning or replacement
