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.

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

Protected Choke Lever/Knob
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 or 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.
