STIHL Guard

Getting peppered by flying grass and small stones isn’t just annoying—it slows you down. This STIHL protective guard places a tough, impact-resistant shield between you and the debris so you can trim with confidence and keep your focus on a clean finish.

Designed for STIHL FS 45 and FS 50 trimmers/brushcutters, it wraps around the rear of the mowing head to deflect clippings and grit right at the source. Whether you use a line head or a PolyCut head, it’s a simple upgrade that makes your work safer and more controlled.

Where it excels

• Edging along paths and driveways where loose stones can fly
• Trimming around beds and borders without showering mulch
• General garden maintenance with line or PolyCut heads

Why this guard helps

Real-world handling

The half-circle design sits close to the rear of the head, intercepting debris without feeling bulky. Once installed correctly, you’ll notice fewer interruptions to clear clippings from clothing or eyewear and a clearer view of your cutting line.

After fitting the guard, run the trimmer at low speed for a few seconds to confirm there’s no contact with the head and that debris is being deflected correctly.
