This heavy-duty professional bike-handle trimmer has a low exhaust emission engine and good power-to-weight ratio.

Landscaping professionals looking for a simplified and convenient trimming solution will love the STIHL FS 131 trimmer. With its low exhaust 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. Improved air filtration and the STIHL exclusive IntelliCarb™ technology make this trimmer a great choice for pros, but the cherry on top is the solid steel drive shaft that accepts a wide range of heavy-duty cutting heads, including metal blades.

Air Filter Cover

Easily remove the cover for fast and easy filter cleaning or replacement.

Anti-Vibration System

STIHL has a system for minimizing the vibration levels of handheld outdoor power equipment. The STIHL anti-vibration system helps reduce operator fatigue and provides a more comfortable working experience.

Bike Handle

When used in conjunction with a harness, the bike handle allows the machine to be easily guided, enabling a smooth horizontal mowing action to cover large areas quickly and efficiently. With soft grips for increased comfort, the bike handle provides greater control and helps reduce operator fatigue.

Fully-Lined Drive Shaft

A lined shaft provides smooth operation and less vibration.

Heavy-Duty Steel-On-Steel Clutch

Centrifugal clutch is designed to reduce slippage.

High-Tech Polymer Housing

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

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.

Made in America

A majority of STIHL products sold in America are made in America of U.S. and global materials.

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

The choke is protected to help prevent damage.

Protected Spark Arrestor Muffler

Large baffles reduce noise level and contain a screen designed to reduce the emission of sparks.

Protected Spark Plug

The spark plug is protected yet easy to change.

Protected on Enclosed Control Cables

Dangling and loose wires are eliminated.

Purge Pump Primer

By pressing the bulb, this small fuel pump delivers fuel to the carburetor, reducing the number of starting pulls needed after an extended break between uses.

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.

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.

Simplified Starting Procedure

To get started, users 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. The tool will be ready to start again when the user is ready to get back to work.
