Stihl RG-KM – Rotary Cutting Head Attachment

STIHL RG-KM: The “Zero-Projectile” Revolution in Surface Weeding

Forget everything you know about traditional string trimmers. The STIHL RG-KM Rotary Cutting Head is a specialized KombiTool designed for one mission: surgical weed removal on “high-risk” surfaces like gravel, asphalt, and paved kerbs. Unlike a spinning line that flings stones like bullets, the RG-KM uses a high-torque reciprocating twin-blade system—essentially a heavy-duty “scissor” action—that cuts vegetation without the high-velocity centrifugal force. This low-spin engineering allows you to work with total confidence just 5 meters from people and 3 meters from glass or cars, making it the primary choice for Irish municipal contractors, school caretakers, and property managers who need a chemical-free weed solution that won’t shatter a patio door or a parked car’s window.

• “Safe-Zone” Proximity Rating: The only tool in the range that officially allows for reduced safety distances ($5\text{m}$ for people vs the standard $15\text{m}$), allowing you to maintain busy car parks and public walkways without shutting down the entire area.

• 120° Rotatable “Triple-Life” Blades: The circular blades are designed so you can rotate them twice before they ever need sharpening. Since only the front 120-degree arc does the work, you effectively get three blades for the price of one.

• Anti-Clog Reciprocation: Because the blades move back and forth rather than spinning, they don’t “vacuum” or wrap long, stringy weeds or damp grass around the gearbox—a common failure point in traditional heads.

• Chemical-Free Surface Scouring: The heavy-duty steel blades are robust enough to be pressed directly into gravel or against tarmac to “scour” out weeds at the root, providing a mechanical alternative to expensive and restricted herbicides.

• Impact-Resistant Rider Plate: The underside features a heavy-duty protective dish that allows the tool to glide over hard surfaces, protecting the cutting gear and reducing the lifting effort for the operator.

• Universal Kombi-Lock System: Instantly swap your blower or hedge trimmer for the RG-KM on any professional KombiEngine (KM 91 R, 94 R, 111 R, 131 R, or the battery KMA 130 R/135 R).
