Fennoral 586922701 Mulch Plug Compatible with Husqvarna LC221, L421P, LC221AH, LC221A Lawn Mowers

What It Is

The Fennoral 586922701 Mulch Plug is an aftermarket replacement part designed to block the side-discharge chute on specific Husqvarna walk-behind mowers, forcing grass clippings to circulate inside the deck for finer mulching. It’s intended for operators who want to switch from bagging or side-discharge to mulching without buying a full mulching kit.

Fitment & Compatibility

Before buying, verify your mower’s deck size and model number. This plug is confirmed to fit Husqvarna LC221, L421P, LC221AH, and LC221A models with a 21-inch stamped steel deck. It replaces OEM part 586922701. Check your mower’s model tag (usually under the seat or on the deck’s rear edge) – if it’s one of those four, it should match. Measure the discharge opening width (roughly 6.5–7 inches) to confirm. This is an aftermarket part, so it may differ slightly in plastic thickness or latch shape from the OEM plug. If your deck has a different design (e.g., fabricated deck or larger opening), it won’t fit.

Key Things to Know

• Build quality: Fennoral’s plug is made of molded plastic. Some users report it’s slightly less rigid than the OEM Husqvarna part, so handle carefully during installation to avoid cracking the tabs.
• Installation difficulty: Easy – just slide the plug into the discharge chute until it clicks into place. No tools required. Removal is the reverse: press the release tab and pull out.
• Common gotcha: If your mower has a mulching blade kit installed, this plug alone won’t improve mulching performance. The plug only blocks the discharge; you need a dedicated mulching blade or baffle kit for finer clipping recirculation.
• Fitment check: The plug’s latch may feel loose on some decks. If it rattles during operation, apply a small piece of foam tape on the inner contact edge to tighten the seal.

Should You Buy It

If you own one of the listed Husqvarna 21-inch walk-behind mowers and want a quick, low-cost way to switch to mulching mode without buying a full kit, this plug is a practical choice. It’s not as durable as OEM, but for occasional use or as a backup, the $21 price and easy install make it a solid value. Avoid it if you need a perfect factory fit or plan to mulch heavy, wet grass regularly – in that case, stick with the genuine Husqvarna part.
