Landscaping professionals that demand power in their mowing applications will love the STIHL FS 111 trimmer. With its low exhaust emission, 31.44 cc engine, grass, and tall, thick weeds don't stand a chance. Because it features a larger fuel tank, the previous model 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.
