#631-05195A 42" & 46'' Decks Mulching Cover Fits Lawn Mower RZT-42 XT1-LT42 XT2-LX42 Durable New Replacement Parts for Cub Cadet

What It Is

This is a mulching cover plate for 42-inch and 46-inch Cub Cadet cutting decks. It replaces the side-discharge chute to redirect grass clippings back into the blade chamber for finer cutting, which improves mulching performance on RZT-42, XT1-LT42, and XT2-LX42 models.

Fitment & Compatibility

Confirm your deck size is exactly 42" or 46" (measure deck housing width, not cutting path). This aftermarket part fits Cub Cadet models RZT-42, XT1-LT42, XT2-LX42, and select XT2-LX46 decks. It does not fit RZT-50, XT1-LT46, or any 54" decks. Compare with OEM part number 631-05195A. Check that your deck has the same three-hole mounting pattern and that the existing chute hinge pins are in good condition—worn pins can cause poor seal.

Key Things to Know

• Quality variance: With a 3.3-star rating, some users report thin plastic that may warp or crack under heat or impact. Inspect for burrs before installation.
• Easy install: No tools needed—snaps over the discharge opening using existing hinge pins. Takes under 5 minutes.
• Common gotcha: If your deck has a side-discharge chute spring, you may need to remove it first. This cover does not include new pins or hardware.
• Performance note: Best for dry, short grass. Thick or wet grass may clog without a dedicated mulching blade kit—consider pairing with high-lift blades.

Should You Buy It

Buy this if you need a budget-friendly mulching cover for a 42" or 46" Cub Cadet deck and your original is cracked or missing. Skip it if you want OEM-grade durability, have a 50"+ deck, or regularly mow tall/damp grass—invest in a sturdier plate or full mulching kit instead.
