Mower Deck Mulch Cover Fits AYP Fits Husqvarna 46" Twin Blade Mower Decks

What It Is

This is a metal cover plate designed to replace the discharge chute on a 46-inch twin-blade mower deck, turning it into a mulching deck. It traps grass clippings inside the deck for finer cutting and re-deposition.

Fitment & Compatibility

• Deck size: Only fits 46-inch twin-blade mower decks (three-blade or 42-inch decks won’t work).
• Brand/model: Listed for AYP (American Yard Products) and Husqvarna, but also fits Craftsman, Poulan Pro, and McCulloch models with the same 46" twin-blade deck. Check your deck’s shape—this cover uses the same bolt pattern as the OEM discharge chute.
• OEM vs aftermarket: This is an aftermarket part. The OEM equivalent is Husqvarna 532402370. If your deck has a different chute pattern, it won’t bolt up.
• Measurements: The cover itself is roughly 4" x 8" with a curved lip. Measure the mounting hole spacing on your existing chute (center-to-center) before buying.

Key Things to Know

• Quality concern: The single 2.0-star review suggests fitment or durability issues—likely thin metal or imprecise hole alignment.
• Installation difficulty: Easy—remove two bolts from the discharge chute, swap the cover, and reinstall. No cutting or drilling if the holes line up.
• Common gotcha: This cover may not seal tightly against all deck variations, causing clippings to escape from the sides. Expect some blowout on uneven ground.
• Mulching performance: You’ll still need sharp mulching blades (sold separately) for best results. This cover alone won’t create a fine mulch.

Should You Buy It

Only if you already own a 46" twin-blade AYP/Husqvarna deck and need a budget mulch cover for occasional use. For better sealing and durability, spend a few dollars more on the OEM part or a thicker aftermarket alternative. If you mulch weekly, skip this—poor performance reports make it a gamble.
