STIHL Protective Guard for Mowing Heads Ø 420 mm

If flying debris keeps slowing you down while trimming, this STIHL protective guard helps you work with confidence again. It deflects stones and clippings when using line or PolyCut mowing heads on your STIHL brushcutter or grass trimmer.

Made from robust, impact-resistant plastic, the half-round shield wraps the rear of the mowing head to stop ejected material right where it leaves the head—so you can focus on clean, controlled cutting.

Where it shines

• Edging along paths and driveways with loose gravel
• Trimming around trees and borders without scattering debris
• Maintaining rough grass where stones and twigs are common
• General brushcutting with line or PolyCut heads

Why this guard helps

• Blocks debris at the source for safer operation
• Durable, shock-resistant plastic stands up to knocks
• Wide Ø 420 mm coverage for effective shielding
• Compatible with a broad range of STIHL machines

In daily use
