33" Mulch Cover Compatible with MTD, Cub Cadet CC760, CC760ES, CC800, DW33, Wide-Cut 833E 833R 933E Lawn Mower Mulch Plug, Replace# -631-04252, 1910919

What It Is

This is a replacement mulch plug (also called a mulch cover or deflector) for select 33-inch wide-cut MTD and Cub Cadet walk-behind mowers. It blocks the grass discharge chute so blades recirculate clippings for finer mulching, eliminating bagging in most normal conditions.

Fitment & Compatibility

• Deck size required: 33-inch cutting deck only. Measure your deck width from blade tip to blade tip—anything smaller or larger won’t seal properly.
• Directly fits: Cub Cadet CC760, CC760ES, CC800, DW33, Wide-Cut 833E, 833R, 933E. Also fits select MTD models with the same deck and chute design.
• OEM cross-references: Replaces OEM part numbers 631-04252 and 1910919. If your current part ends in either number, this is a direct swap.
• Check before buying: Look at the chute opening shape—this plug has a flat, rectangular flange with two mounting holes. If your chute uses a different latch or has a curved/angled flange, it won’t fit. Also confirm you have the original chute cover hardware (screws/bolts); this part comes as just the plastic plug, no fasteners.

Key Things to Know

• Material quality: Molded plastic, similar to OEM. A few reviews note it can warp in direct sun over time if left on the mower between uses. Store indoors or remove when not mulching.
• Installation difficulty: Easy—remove chute cover, align plug over opening, and secure with existing bolts. No tools beyond a screwdriver or socket. Takes under 5 minutes.
• Common gotcha: This is a mulch plug, not a full mulching kit. It only blocks the discharge; you still need a mulching blade (sold separately) for best results. Using it with standard blades will leave clumps.
• Fitment note: On some CC800 models, the plug may contact the blade tip if the deck is bent or the blade isn’t centered. Spin the blade by hand after install to check clearance.

Should You Buy It

Buy this if you have one of the listed 33-inch Cub Cadet or MTD wide-cut mowers and want a cheap, direct-replacement mulch plug to swap between bagging and mulching. It’s fine for occasional use, but consider an OEM part if you mulch heavily or leave the plug on all season—the aftermarket plastic is less durable over time.
