What It Is

This Cub Cadet OEM mulch kit (part #190-116) converts select LT and GT series lawn tractors from side-discharge or bagging to fine-cut mulching. It includes a block-off plate, mulch baffle, and hardware to recirculate clippings for a clean, fertilizer-free finish.

Fitment & Compatibility

• Deck sizes: 42-inch and 46-inch fabricated decks on Cub Cadet LT and GT models (e.g., LT 2150, 1170, 1527, 1525, 2130, 2135).
• Cross-reference numbers: OEM-190-112, 731-2363, 731-1643A, 7311643A, 731-1643.
• Check before buying: Measure your deck width and confirm it’s a fabricated (not stamped) deck. Verify your mower model from the serial plate under the seat or hood. This kit will not fit stamped decks or zero-turn mowers.
• OEM vs aftermarket: This is genuine Cub Cadet—guaranteed fit for listed models. Aftermarket kits may save $15–20 but often require tweaking or lack gaskets.

Key Things to Know

• Installation difficulty: Moderate. You’ll need a socket set and 30–45 minutes. No cutting or drilling required.
• Quality: Heavy-gauge steel baffle and precision-cut plate. Holds up to years of use if kept clean.
• Common gotcha: The block-off plate gasket can shift during install—apply a thin bead of silicone or use double-sided tape to hold it in place.
• Performance: Best in dry grass; wet clippings may clump. Run at full throttle and overlap passes by 2–3 inches.

Should You Buy It

Buy if you own one of the listed Cub Cadet LT/GT models with a 42- or 46-inch fabricated deck and want a clean, no-bagging lawn. Skip if you bag clippings or have a stamped deck—this kit won’t fit. At $89, it’s a fair price for OEM reliability.
