The Honda 21913-VF9-V30 Grass Guard B is a genuine OEM replacement designed for UMK422 and UMK431 trimmers. Sourced directly from Honda, this guard is built to the exact specifications of the original component it replaces. Fitment covers both the UMK422 and UMK431 — verify your model against the compatibility table to confirm the correct application for your unit.
Key Features
- Genuine Honda OEM — manufactured to Honda's original specifications, ensuring the guard aligns and mounts correctly on your trimmer without modification.
- Exact Replacement — directly replaces the original Grass Guard B on UMK422 and UMK431 trimmers, restoring proper guarding function to the cutting head area.
- Serial Number Awareness — Honda supersedes parts at production breaks, so check your trimmer's serial number against the fitment table before ordering to confirm part number 21913-VF9-V30 is correct for your unit.
The Grass Guard B is the protective shield positioned near the cutting head of the trimmer. It deflects cut material and debris away from the operator during use, and its presence is essential to keeping the trimmer running safely and effectively in its intended role. A cracked, broken, or missing guard leaves the cutting zone exposed and compromises the machine's ability to function as designed — replacing it with a correct OEM part restores the trimmer to its original working condition.
