2 Packs Lawn Tractor 46-in Deck Mulch Cover Assembly Replacement for Craftsman T2400 Riding Mower, Craftsman 46" YT3000 Riding Mower

What It Is

This is a two-pack of mulch cover assemblies designed for 46-inch lawn tractor decks, specifically for Craftsman T2400 and YT3000 riding mowers. It replaces the factory cover that blocks the side discharge chute, forcing clippings to recirculate under the deck for finer mulching.

Fitment & Compatibility

Before buying, confirm your deck is exactly 46 inches (measure blade tip to tip). This assembly fits Craftsman T2400 and YT3000 models with 46-inch fabricated or stamped decks. It is an aftermarket replacement for OEM part numbers 532178968 or 178968. Check that your deck’s mounting holes align—these covers use two bolts near the chute opening. Not compatible with 42-inch or 54-inch decks, or non-Craftsman brands.

Key Things to Know

• Build quality varies: Some users report thin plastic that cracks if overtightened or hit by debris. Inspect for sharp edges after installation.
• Installation is simple: Remove the old chute deflector (if present), align the cover, and secure with the included bolts. No special tools needed—just a socket wrench.
• Common gotcha: The cover may not seal perfectly on older decks with bent or rusted mounting tabs. You might need to add a rubber gasket or shim for a tight fit.
• Two-pack value: You get two covers, useful for spares or if you frequently mulch and want a quick swap without cleaning.

Should You Buy It

This is a decent budget option if you need a mulch cover for a Craftsman 46-inch mower and don’t want to pay OEM prices. It works as intended for light residential use, but if you have a heavy-duty or commercial mower, or want a sturdier metal cover, look elsewhere. The low review count and mixed ratings suggest it’s a basic replacement, not an upgrade.
