42" Deck Mulch Plug Kit Compatible with FITSHusqvarna Craftsman Poulan Mower MP42 24142 198383 954040501 Includes Hardware

What It Is

This 42-inch deck mulch plug kit blocks the discharge chute on side-discharge mowers, forcing grass clippings to recirculate under the deck for finer cutting and natural lawn fertilization. Designed for Husqvarna, Craftsman, and Poulan models with a 42-inch fabricated or stamped deck.

Fitment & Compatibility

Before buying, confirm your deck size is exactly 42 inches (measured blade tip to blade tip). This kit fits most Husqvarna, Craftsman (including LT1000/2000/4000 series), and Poulan Pro models with a standard oval discharge opening. OEM part numbers: 532198383, 532954040501, MP42, 24142. Check that your deck has two pre-drilled holes near the chute opening—some newer decks require drilling. Aftermarket, not OEM, but includes all necessary hardware (bolts, nuts, washer, and a foam seal strip).

Key Things to Know

• Installation is 10-15 minutes: Remove the existing chute deflector, slide the plug into the opening, and secure with provided bolts. No special tools beyond a socket wrench.
• Foam seal strip is critical: If not pressed firmly against the deck, clippings will leak and reduce mulching efficiency. Replace if torn.
• Not for bagging or side-discharge: Once installed, the mower is dedicated to mulching. Switching back requires removing the plug.
• Quality note: The plastic plug is durable but can warp if left in direct sun for extended periods. Store mower under cover.

Should You Buy It

If you have a 42-inch Craftsman, Husqvarna, or Poulan mower and want to convert it for mulching without spending $40+ on an OEM kit, this is a solid, budget-friendly choice. It’s easy to install and works well for typical residential lawns, but skip it if you frequently switch between mulching and bagging—the plug is a bit tedious to remove and reinstall.
