Bad Boy Mulch Kit

This kit is specifically designed for 54-inch decks on 2017-present MZ, MZ Magnum, and MZ Rambler models, as well as 2020-present ZT Avenger models. Please verify your specific model year and deck size before purchasing to ensure compatibility.

The wavy blades are designed to create extra lift and turbulence under the deck. This motion chops grass clippings into finer pieces, which decompose faster and return nutrients to your soil more efficiently than standard flat blades.

The kit is designed for a straightforward installation that bolts directly to the underside of your mower deck. While it includes all necessary hardware and instructions, you will need basic tools and should ensure the mower is safely lifted or blocked before beginning.

Yes, the mulch plug is designed to block the discharge chute completely to keep clippings contained. If you need to switch back to side discharge for taller or wetter grass, you will need to remove the plug and swap the blades back to your standard set.

You should maintain these blades just as you would standard mower blades. Inspect them for dullness or damage every 20 to 25 hours of use, or sooner if you notice the grass tips looking frayed rather than cleanly cut.
