Equipped with a simplified starting procedure, the STIHL FS 251 is a heavy-duty trimmer built for pros with no time to waste. 

Designed with a powerful low exhaust emission engine, the STIHL FS 251 saves on fuel and operating costs without losing any of the power. 

FEATURES

• Powerful Low Exhaust Emission Engine - A powerful low exhaust emission engine saves users fuel and operating costs without losing the power they count on to get the job done.
• STIHL ElastoStart™ - The ElastoStart™ starter handle is a feature of STIHL. It is a starting grip with a built-in shock absorber that helps reduce the effort when pulling on the starter cord. The ElastoStart™ starter grip noticeably reduces the sudden peak forces (compression) normally felt during cranking. The forces which occur at the grip after the first compression stroke are smoothed out.
• TapAction™ AUTOCUT® Cutting Head - TapAction™ allows users to adjust the line length simply by tapping the cutting head against the ground.
• 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.
• 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.
• Anti-Vibration System - The STIHL anti-vibration system helps reduce operator fatigue and provides a more comfortable working experience by minimizing the vibration levels of handheld outdoor power equipment.
• 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.
