Features

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.
Lining provides smooth operation and low vibration.
Centrifugal clutch is designed to reduce slippage.
Housings are lightweight, withstand greater impact, and are corrosion-resistant.
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.
Loop handle grass trimmers and brushcutters are ideal for trimming between bushes and shrubs and other areas where space is limited.
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 helps makes it easier to complete tasks so the operator’s hand never has to leave the handle.
The spark plug is protected yet easy to change.
Dangling and loose wires are eliminated.
A small fuel pump delivers fuel to the carburetor when pushed, reducing the number of starting strokes required following extended breaks in operation.
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.
TapAction™ allows users to adjust the line length simply by tapping the cutting head against the ground.
This safety feature must be depressed before the trigger can be activated.
Easily check the fuel level before starting work. If fuel is needed, the upright position makes the tank easier to fill.
Features a redesigned gearbox delivering a 13.5% increase in torque. This boost in power translates to faster cutting speeds and noticeably cleaner results, even in dense or overgrown areas. Whether you're tackling thick brush or fine trimming, this high-torque upgrade ensures professional-grade performance every time.
Comfort meets functionality with the new 35-degree angled gearhead, replacing the previous 30-degree design. This adjustment enhances ergonomics for various users’ statures to improve maneuverability. Whether you're trimming for minutes or hours, the new angle helps maintain a natural posture and is designed to reduce fatigue.
Efficiency gets a major upgrade with the expanded cutting radius—now 17.7 inches, up from 16.5 inches. This wider reach allows users to cover more ground with fewer passes, saving time and effort on every job. Complemented by a newly designed deflector with skirt, the increased radius also improves debris management for a cleaner trimming experience.
