Product Description

Landscaping professionals looking for a simplified and convenient trimming solution will love the STIHL FS 131 trimmer. With its low-emission, 36.3 cc engine and a larger fuel tank than the previous model, the FS 131 delivers 30% longer run times. Its bike-handle design includes rubberized grips for enhanced grasp and comfort. The trimmer also features one touch stop and an easy, three-step starting procedure enabled by the semi-automatic choke lever. All of that, plus an improved air filtration and STIHL exclusive IntelliCarb™ technology. The cherry on top? The solid steel drive shaft accepts a wide range of heavy-duty cutting heads, including metal blades.

With soft grips for increased comfort, the bike handle provides greater control and helps reduce operator fatigue.

  • Shoulder Strap / Carrying System
    Using a shoulder strap or carrying system helps distribute the weight of the equipment for increased operator comfort and improved maneuverability.

    The IntelliCarb™ Compensating Carburetor measures the air pressure on the clean side of the air filter and adjusts the metering diaphragm in the carburetor. This keeps the RPM at a consistent level, even when the air filter begins to clog.

    The central wing nut enables easy adjustment without the use of tools. For transportation and space-saving storage, the handle can be rotated 90°.
