960120040 Riding Mower Mulch Compatible with Craftsman 54" RZ5424 Z254 LGT2654with Hooks 187298 Riding Plate Cover Lawn Mowers Kit

What It Is

This is a mulching plate/cover kit (part 960120040) designed to convert a side-discharge Craftsman riding mower into a mulching mower. It blocks the discharge chute so grass clippings are recirculated and finely chopped under the deck.

Fitment & Compatibility

Check three things before buying:

• Deck size: Confirmed for 54-inch decks only (not 42", 46", or 50").
• Model fit: Compatible with Craftsman RZ5424, Z254, LGT2654, and other models using the OEM 187298 plate. Verify your mower’s model number on the frame sticker.
• Hooks: Includes hooks that attach to the deck’s discharge opening. If your deck lacks these mounting points, it won’t fit.
• Measurements: Plate dimensions are roughly 12" x 8" (actual shape is curved to match the deck). Compare to your current discharge opening.

Key Things to Know

• Quality: Mixed reviews—some report thin metal that bends or rusts quickly. A few note poor fit requiring bending or shimming.
• Installation: Simple bolt-on job (10-15 minutes). You may need to remove the existing chute deflector. No cutting or drilling.
• Gotcha: The plate may not seal perfectly against all deck shapes, leading to clumping or uneven mulching. Sealant or weatherstripping can help.
• Performance: Works best with a mulching blade set (sold separately). Using standard blades reduces mulching effectiveness.

Should You Buy It

This is a budget-friendly option if you already own a compatible Craftsman 54" deck and want occasional mulching without buying a dedicated mulching mower. But expect possible fitment tweaks and mediocre durability—if you need a perfect seal or heavy-duty use, consider an OEM 187298 plate or a full mulching kit from the manufacturer.
