CUB CADET 19A70057GFP Xtreme Mulching Kit 60" Decks Ultima ZT2 ZT3 60 KW FAB 19A70057100

What It Is

The Cub Cadet 19A70057GFP Xtreme Mulching Kit is a factory-engineered set of baffles, covers, and hardware that converts 60-inch fabricated decks on select Ultima ZT2, ZT3, and other Cub Cadet zero-turn mowers from side-discharge to high-performance mulching. It’s designed for operators who want finer clippings, less bagging, and improved nutrient recycling on residential or commercial turf.

Fitment & Compatibility

Before buying, confirm your mower has a 60-inch fabricated (FAB) deck—this kit will not fit stamped decks. Compatible models include Cub Cadet Ultima ZT2 (e.g., ZT2 60), ZT3 (e.g., ZT3 60 KW), and the 19A70057100 series. Check your mower’s model number on the frame tag (not just the deck) to ensure it ends in “60” and matches the 19A70057GFP part number. The kit is OEM, so no aftermarket adapter or modification is needed if your deck is listed. Measure your deck’s overall width and baffle mounting holes; they should align with the kit’s pre-drilled brackets. If in doubt, cross-reference your mower’s serial number with Cub Cadet’s official fitment chart.

Key Things to Know

• Installation difficulty: Moderate. Expect 30–60 minutes; you’ll need basic hand tools (socket set, wrenches) and patience to remove the existing discharge chute and bolt on the mulching baffles. A second person helps for alignment.
• Quality: Heavy-gauge steel baffles hold up well, but some users report slight gaps at the deck edge—check tightness after first mow. Paint finish matches OEM but can chip if bolts are overtightened.
• Performance: Works best with sharp, high-lift blades (not included). Dull blades or wet grass will cause clumping. You’ll need to mow more frequently and at a slower ground speed for even mulching.
• Gotcha: The kit replaces the side-discharge chute entirely—you cannot quickly switch back. If you occasionally bag or discharge, consider a quick-change conversion instead.

Should You Buy It

Buy this kit if you own a Cub Cadet Ultima ZT2/ZT3 with a 60-inch fabricated deck, want a cleaner lawn without bagging, and are willing to mow on a regular schedule. It’s a solid OEM upgrade for finer clippings and less cleanup, but skip it if you frequently mow tall/wet grass or need the flexibility to switch between discharge modes.
