HECASA Mulching Cover Compatible with Craftsman T2100 | Troy-Bilt TB46 | Cub Cadet 42"&46'' Deck Mulch Kit Lawn Mower Mulch Plug Replacement for 631-05195A Black

What It Is

This is an aftermarket mulching cover (or mulch plug) that replaces the discharge chute or bagger opening on select 42-inch and 46-inch lawn mower decks. It recirculates clippings under the deck for finer cutting and natural fertilization, designed for Craftsman T2100, Troy-Bilt TB46, and Cub Cadet models with a 42" or 46" deck.

Fitment & Compatibility

Before buying, verify your mower’s deck size (42" or 46") and model series. This cover is an aftermarket replacement for OEM part 631-05195A. It fits:

• Craftsman T2100 (any deck size in the T2100 series)
• Troy-Bilt TB46 (46" deck models only)
• Cub Cadet 42" and 46" decks (e.g., LT42, XT1, XT2, RZT models with those deck sizes)

Check: Measure your deck’s discharge opening width and bolt pattern. This cover uses two bolts (typically 1/4" or 5/16") spaced about 4-5 inches apart. If your deck has a different bolt spacing or uses a clip-on design, it won’t fit. Confirm your mower’s model number (stamped on the deck or frame) against HECASA’s official fitment list—generic “42"/46"” claims can be misleading.

Key Things to Know

• Quality is mixed: Several users report thin plastic that can crack or warp under heat/sun. Expect 1-3 seasons of use with normal care.
• Installation is simple: Remove the discharge chute or bagger adapter, align the cover over the opening, and bolt it on. No cutting or drilling required.
• Check for existing hardware: The cover does not include bolts or washers. You’ll need two bolts (1/4" or 5/16" depending on your deck) and lock nuts.
• Bagger/discharge conflict: This cover blocks the bagger chute and side discharge. You cannot use a bagger or side-discharge attachment with it installed.

Should You Buy It

Buy this if you own a Craftsman T2100, Troy-Bilt TB46, or Cub Cadet with a 42" or 46" deck and want a low-cost way to mulch without buying an OEM kit. It’s a decent budget option for light-duty mowing on flat lawns, but skip it if you need heavy-duty durability or have a non-standard deck design. For the price, it’s worth trying if you’re handy with a wrench, but expect to replace it sooner than an OEM part.
