Features

Loop Handle (R)
Loop handle grass trimmers and brushcutters are ideal for trimming between bushes and shrubs and other areas where space is limited.
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.
Built in the USA
A majority of STIHL gasoline-powered units sold in the United States are built in the United States from domestic and foreign parts and components.
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.
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.
Tool-Free Handle Adjustment
The central wing nut enables easy adjustment without the use of tools. For transportation and space-saving storage, the handle can be rotated 90°.
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.
Fully Lined Drive Shaft
Provides smooth operation and less vibration
High Tech Polymer Housing
Housings are lightweight, withstand greater impact and are corrosion-resistant.
Protected Choke Lever/Knob
Helps prevent damage.
Throttle Trigger Interlock
