What It Is

This mulching kit replaces the side-discharge chute on 46-inch Cub Cadet mower decks, allowing grass clippings to be recut and deposited as fine mulch. It’s designed for both zero-turn and lawn tractor models with a 46" fabricated deck.

Fitment & Compatibility

Before buying, confirm your mower has a 46-inch fabricated deck (not stamped). This kit fits Cub Cadet XT1-LT46, XT2-LX46, LTX-1045, LTX-1046, RZT-L46, RZT-S46, and RZT-SX46 zero turn mowers. It replaces OEM part numbers 19A30005100, 19A30005791, and 19B30005791. Measure your deck spindle-to-spindle distance to ensure the 46" width; check the deck model number (stamped on the deck housing). This is an aftermarket part—not genuine Cub Cadet—so verify your specific mower series (e.g., XT1 vs. XT2) as some deck mount patterns differ slightly.

Key Things to Know

• Build quality concerns: At 3.2 stars, reviews note thinner gauge steel than OEM, leading to potential warping or cracking over time. Inspect for sharp edges on installation.
• Installation difficulty: Moderate—requires removing the side-discharge chute and attaching the kit with included hardware. No drilling needed, but some users report misaligned bolt holes requiring filing or adjustment.
• Mulching performance: Works best with dry grass; wet or tall grass may clog or leave clumps. You may need to mow more frequently (cut no more than 1/3 of grass height).
• Warranty note: Aftermarket kits may void your mower’s warranty if it’s still active. Check your warranty terms before installing.

Should You Buy It

Buy this kit if you want an affordable mulching option for a 46" Cub Cadet deck and are willing to accept potentially lower build quality than OEM. It’s a decent budget pick for occasional mulching on dry lawns, but if you need heavy-duty, long-term durability or have a mower still under warranty, spend extra on the genuine Cub Cadet 19A30005100 kit.
