What It Is

This is a genuine Cub Cadet 42-inch mulch kit (OEM part 19A70041GFP) designed to convert bagging or side-discharge mowers into a mulching system. It’s intended for select Cub Cadet zero-turn and lawn tractor models (RZT, ZT1, XT1, XT2, SX42, S42, LX42) with 6-point star blade systems.

Fitment & Compatibility

• Deck size: Only fits 42-inch cutting decks with a 6-point star spindle pattern (not round or 5-point). Measure your deck’s spindle center-to-center spacing—it should match the kit’s baffle and blade layout.
• Models: Confirmed for Cub Cadet RZT EFI 42, ZT1 42, XT1 42, XT2 42, SX42, S42, and LX42. Check your mower’s model number (e.g., 13APA1CT056) against the kit’s OEM number (19A70041GFP). Not compatible with older 42-inch decks using round spindles.
• OEM vs aftermarket: This is OEM Cub Cadet; aftermarket kits (e.g., Oregon) may fit but often lack the exact baffle shape or hardware. Use OEM to avoid poor mulching or vibration.
• What to verify: Your deck must currently have a side-discharge chute or bagger attachment—this kit replaces those parts. Also confirm you have the required 6-point star blades (not included in some models).

Key Things to Know

• Installation: Moderate difficulty (30–60 minutes). You’ll remove the existing discharge chute, install the mulch baffle, and swap blades. A socket wrench and torque wrench (blade bolts: 70–90 ft-lbs) are needed.
• Quality: Sturdy steel baffle and included hardware. The 6-point star blades are designed for fine mulching, but they dull faster than standard blades on thick grass or debris.
• Common gotcha: The kit does not include a mulch plug for the deck opening—check if your model requires one (some have a built-in cover). Also, the baffle may not clear tall grass; mow in stages for best results.
• Performance: Works best with dry, short grass (2–3 inches). Wet or overgrown grass will clog, requiring frequent cleaning.

Should You Buy It

If you own a compatible Cub Cadet 42-inch model with a 6-point star deck and want to eliminate bagging or side-discharge for a cleaner lawn finish, this OEM kit is a solid, well-built choice. It’s ideal for homeowners who mow regularly and value fine clippings that decompose quickly. Avoid if you have a non-Cub Cadet deck or a 5-point spindle system.
