STIHL FS 131

A powerful bike-handle trimmer made for professional use, featuring simplified starting and 30% longer run time than the FS 110.

Landscaping professionals that demand power in their mowing applications will love the STIHL FS 111 trimmer. With its low-emission, 31.4 cc engine, grass and tall, thick weeds don’t stand a chance. And because it features a larger fuel tank, the FS 111 delivers 30% longer run times when compared to the FS 110. Its bike-handle design also includes rubberized grips for enhanced comfort and leverage. The trimmer features one touch stop and a simplified starting procedure enabled by the semi-automatic choke lever. Add to that an improved air filtration and STIHL exclusive IntelliCarb™ technology for maximum RPM when air filter begins to clog. Need to cut down heavy brush or saplings? The solid steel drive shaft accepts a wide range of heavy-duty cutting heads, including metal blades.

Model Features

Reduced-Emission Engine Technology – Caring for Nature: The STIHL Inc. “Caring for Nature” seal identifies its powered products that are more environmentally conscious, producing zero or low exhaust emissions. STIHL Inc. defines “low exhaust emissions” as being cleaner than EPA and/or CARB exhaust emission standards.
Simplified Starting Procedure: To get started, simply pump the fuel primer, set the choke and pull the starter cord. The built-in stop switch allows the user to turn off the engine with a simple press of the button. When the engine is off, the throttle lock automatically returns to the “start” setting. Your power tool will be ready to be started when you’re ready to get back to work.
IntelliCarb™ Compensating Carburetor: 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.
Tool-Free Handle Adjustment: The central wing nut enables easy adjustment without the use of tools. For transportation and space-saving storage, the handle can be rotated 90°.
