631-05195A 631-05195 Lawn Mower Mulch Plug Kit for Cub Cadet 42" & 46" Mulch Plug 19B30005 19A70041 63105195A LTX-1045 LTX-1046VT LTX-1050KH Fits 2012 and After, Include Installation Hardware

What It Is

This is a mulch plug kit (part numbers 631-05195A / 631-05195) that replaces the side-discharge chute on select Cub Cadet 42-inch and 46-inch mower decks. It traps clippings inside the deck so the blades cut them repeatedly into fine mulch, which is then deposited back onto the lawn.

Fitment & Compatibility

Before buying, confirm two things: your deck size (must be 42" or 46") and your Cub Cadet model year (2012 and later). This kit fits specific LTX series tractors including LTX-1045, LTX-1046VT, and LTX-1050KH, plus any model using OEM part numbers 19B30005 or 19A70041. It will not fit 50" or 54" decks, and it won’t work on older pre-2012 decks without verifying the mounting hole pattern. Measure the width of your deck opening (the chute outlet) and compare to the plug’s dimensions—it should be roughly 7" wide by 4" tall. If your deck uses a twist-lock or slide-in chute design, this plug uses a simple bolt-on method with included hardware.

Key Things to Know

• Installation difficulty: Easy. Remove the side-discharge chute (usually one or two bolts), bolt the mulch plug in its place, and reattach any safety deflector if required. Takes about 10 minutes.
• Quality: The plug is rigid plastic with a metal mounting bracket. It holds up well but can crack if overtightened or if the deck hits a large rock or stump. Hand-tighten bolts only.
• Common gotcha: Some users report the plug doesn’t seal perfectly on older decks with warped or rusted mounting surfaces. Check your deck’s chute opening for damage before installing.
• Mulching performance: This is a plug-only kit—it does not include special mulching blades. For best results, pair with a set of Cub Cadet mulching blades (sold separately). Without them, you’ll get larger clippings and more clumping.

Should You Buy It

If you have a compatible 42" or 46" Cub Cadet from 2012 or later and want to convert from side-discharge to mulching without buying a full mulching kit, this plug is a cost-effective, easy install. It’s not for you if you need a complete mulching system (blades included) or if your deck’s chute opening is damaged or non-standard.
