Mulch Cover 960120040 532187298 Compatible with Craftsman Riding Lawn Mowers Model 54" RZ5424 Z254 LGT2654

What It Is

This is a mulch cover (OEM part number 960120040 / 532187298) designed for Craftsman riding lawn mowers. It replaces the side-discharge chute to block grass clippings from ejecting, forcing them to recirculate under the deck for finer mulching.

Fitment & Compatibility

• Deck size: Fits 54-inch cutting decks only. Do not use on 42”, 46”, or 50” decks.
• Model examples: Compatible with Craftsman RZ5424, Z254, LGT2654, and other 54” deck models from the same era. Check your mower’s model number (stamped under seat or on frame) against the OEM part number.
• OEM vs aftermarket: This is a genuine OEM replacement part, so it bolts directly to factory mounting holes. Aftermarket universal covers may require drilling or modifications.
• Measurements: Cover opening fits the 6.5” x 4.5” discharge port. Mounting holes are 5.5” apart center-to-center. Verify your deck’s discharge opening matches before ordering.

Key Things to Know

• Installation difficulty: Easy – remove two bolts on the discharge chute, swap in the mulch cover, and reinstall bolts. No tools beyond a socket or wrench needed.
• Quality: OEM plastic is durable but can crack if overtightened or hit by debris. Hand-tighten bolts, then add a quarter turn.
• Gotcha: You must also install mulching blades (sold separately) for proper cutting. Standard blades will leave long clippings that clump.
• Gotcha: This cover blocks side discharge only. If you need a bagging setup, this won’t work – it’s strictly for mulching.

Should You Buy It

Buy this if you own a Craftsman 54” deck rider and want to switch from side-discharge to mulching without buying a whole new mower. It’s a direct-fit OEM part, easy to install, and costs less than a tank of gas. Skip it if you prefer bagging or have a different deck size.
