Honda 76266-VG4-020ZA Stuffing Mulch Plug NH105

What It Is

The Honda 76266-VG4-020ZA Stuffing Mulch Plug NH105 is an OEM mulch plug designed to block the grass discharge chute on select Honda lawn mowers, forcing clippings to recirculate under the deck for finer mulching. This part is intended for use with compatible Honda mowers when converting from side-discharge to mulching mode.

Fitment & Compatibility

Before buying, verify your mower’s deck size and model series. This plug fits specific Honda mowers with 21-inch or 22-inch steel decks, including the HRX217, HRR216, and HRS216 series, as well as some HRS and HRC commercial models. Check your mower’s model number (stamped on the deck or under the seat) against Honda’s parts diagram. The plug measures roughly 6 x 4 inches and uses two spring clips to secure into the discharge opening. It is an OEM Honda part, not aftermarket, so fit is precise but limited to the models listed. If your mower has a plastic deck or a different series (e.g., HRB216), this plug will not fit. Always measure your discharge chute opening width and confirm the clip spacing matches.

Key Things to Know

• Installation difficulty: Easy—takes under 2 minutes. Remove the side-discharge deflector, slide the plug into the opening, and snap the clips into place.
• Quality: OEM Honda construction with durable rubber and plastic; holds up well to sunlight and regular use, but the clips can become brittle over time if left in direct sun.
• Common gotcha: This plug only works for mulching—you must also use a mulching blade (sold separately) for proper fine-cut results. If you try to mulch with a standard blade, clippings will be coarse.
• Storage: When not in use, the plug can be stored on the mower’s handlebar clip (if equipped) or kept in a dry place to prevent clip warping.

Should You Buy It

Buy this if you own a compatible Honda mower (HRX217, HRR216, HRS216, or similar) and want a factory-fit, no-hassle way to switch to mulching. It’s a solid OEM part that seals well and lasts, but skip it if your mower isn’t on the compatibility list—aftermarket plugs may work but won’t match the fit or durability. Ideal for homeowners who mulch regularly and want a quick conversion without modifying the deck.
