CUB CADET Mulching Kit 42-inch Deck – 19A70041100 | Fits XT1, XT2, RZT SX Ultima 42

Upgrade your Cub Cadet 42-inch deck with the 19A70041100 Mulching Kit

This OEM mulching kit is designed to complement Cub Cadet RZT SX, XT1, XT2, and Ultima models that use a 42-inch cutting deck. Instead of collecting clippings in a bag, your mower can mulch them into a fine residue that helps cover soil and keep the lawn looking cohesive between visits to the bagger. The result is a lawn with a more even texture and a neater edge where the clippings are evenly dispersed.

The kit includes two mulching blades, a molded plug, mounting hardware, and straightforward instructions. The blades are shaped to match the deck geometry, promoting efficient cutting and consistent mulch size for a more uniform finish across the mowing pass. The molded plug helps seal the discharge area when needed, supporting a cleaner installation with less risk of debris escaping during operation.

What’s included

• Two mulching blades
• Molded plug
• Mounting hardware
• Instructions for installation

Key benefits and real-world use

Mulching converts fresh clippings into a plant-friendly micro-mulch that can stay on the lawn surface longer, promoting soil moisture retention and a greener look after mowing. While outcomes vary with grass type and mowing height, users often notice a neater lawn without the daily chore of bagging.

Two blades offer a balanced cut that helps maintain propulsion and deck performance. The included hardware is sized for a snug fit, and the instructions walk you through a clear sequence, making the upgrade approachable for DIY enthusiasts and pros alike.

Compatibility and installation tips

• Designed for 42-inch decks on Cub Cadet Enduro Series XT1, XT2, and RZT SX lines, including Ultima 42.
• Always consult the original owner's manual to confirm exact fit for your model.

Care and maintenance

After installation, check mounting screws and blade balance periodically. Clean the blades and plug if debris accumulates, and inspect the hardware for signs of wear after the first mowing season.
