Mtd 631-05195A Lawn Tractor Mulch Cover Genuine Original Equipment Manufacturer (OEM) Part

What It Is

The MTD 631-05195A is a genuine OEM mulch cover designed to convert your lawn tractor’s side-discharge deck into a mulching system. It blocks the discharge opening, forcing grass clippings to recirculate and finely chop them for nutrient-rich lawn feeding.

Fitment & Compatibility

Before buying, verify:

• Deck size: This cover fits MTD, Cub Cadet, Troy-Bilt, and Yard Machines tractors with 42-inch or 46-inch stamped steel decks (check your deck’s stamped model number).
• Mounting: Uses the existing discharge chute holes—no drilling required. Measure the distance between mounting holes (approx. 8.5 inches center-to-center).
• OEM vs aftermarket: This is genuine MTD, so it matches factory specs exactly. Aftermarket versions may have looser fit or thinner plastic.
• Model check: Confirm your tractor’s model/serial number via MTD’s parts lookup or your owner’s manual. Common compatible chassis include 13A, 13B, 13W, and 13C series.

Key Things to Know

• Quality: Durable, UV-resistant black plastic that holds up to sun and impacts. Some users report minor warping after prolonged heat exposure, but still functional.
• Installation: Easy—takes 5 minutes with a wrench. Remove the side-discharge chute, align the cover to the deck lip, and secure with the two existing bolts.
• Gotcha: For effective mulching, you must also install a mulching blade kit (sold separately) and keep grass dry and short. The cover alone won’t produce fine clippings.
• Warranty: Covered by MTD’s 1-year OEM parts warranty—keep your receipt.

Should You Buy It

If you own a compatible MTD-family tractor and want to switch from bagging/discharging to mulching without buying a new deck, this is a solid, affordable upgrade. It’s not a magic fix—pair it with sharp mulching blades and proper mowing technique for best results.
