Features
TapAction™ AUTOCUT® Cutting Head
TapAction™ allows users to adjust the line length simply by tapping the cutting head against the ground.
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
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.
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.
Multi-Function Control Handle
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.
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.
