960120040 Mulch Cover Kit W/Mounting Accessories for Craftsman Husqvarna 54" Riding Lawn Mowers RZ5424 Z254 LGT2654, Mulch Plate Cover Hooks Kit Replace 532187298 187298

What It Is

This mulch cover kit (model 960120040) converts an open-discharge mower deck into a mulching deck by blocking the side chute, forcing grass clippings to recirculate and be cut finer. Designed for 54-inch Craftsman and Husqvarna zero-turn and lawn tractors (e.g., RZ5424, Z254, LGT2654).

Fitment & Compatibility

Before buying, verify your mower has a 54-inch fabricated or stamped deck with a standard side-discharge opening. This kit replaces OEM part 532187298/187298 and fits most Craftsman/Husqvarna models with that deck size. Check your deck’s chute mounting holes: they should match the included hooks and plate. If your deck has a quick-release chute latch, this may not be compatible—measure the chute opening width (roughly 6–8 inches) and confirm the plate covers it fully. Not for 46-inch or 50-inch decks.

Key Things to Know

• Installation difficulty: Easy (no special tools), but you’ll need to remove the existing discharge chute or deflector first. Takes 10–15 minutes.
• Quality: Plate is stamped steel with a black powder coat. Some users report slight bending if overtightened, so hand-tighten bolts only.
• Common gotcha: The included mounting hooks may not align perfectly on all deck variants. You might need to drill a new hole or use a washer to shim the fit.
• Performance: Works best with sharp blades and dry grass. Wet or tall grass can clog the deck, so consider a high-lift mulching blade upgrade.

Should You Buy It

If you have a 54-inch Craftsman or Husqvarna riding mower and want to avoid bagging or raking clippings, this is a cheap, effective fix. It’s not for heavy-duty commercial use, but for a residential lawn under an acre, it saves cleanup time. Skip it if your deck has a non-standard chute design or you prefer side-discharge.
