8TEN Mulch Kit for Cub Cadet ZTX5 ZTX4 ZTX6 ZTXS5 ZTXS6 ZTXS4 60-Inch Deck 742P05516 19B70066100 (Toothed Mulching)

What It Is

An aftermarket mulch kit designed to convert a side-discharge Cub Cadet ZTX5, ZTX4, ZTX6, ZTXS5, ZTXS6, or ZTXS4 60-inch deck into a toothed mulching system. It’s meant for operators who want finer grass clipping recutting without bagging.

Fitment & Compatibility

• Deck size must be exactly 60 inches – will not fit 54-inch, 50-inch, or 72-inch decks.
• Model series confirmed: ZTX5, ZTX4, ZTX6, ZTXS5, ZTXS6, ZTXS4. Verify your specific serial number against OEM part numbers 742P05516 or 19B70066100.
• Aftermarket replacement for the OEM Cub Cadet mulch kit – not a genuine Cub Cadet part.
• Check existing deck hardware: This kit uses toothed blades (not standard flat mulch blades). Ensure your deck spindle pattern matches (usually 3-point star or 5-point, but measure bolt circle diameter and center hole size before purchase).
• Baffle clearance: The included baffle inserts must align with your deck’s discharge opening. Measure opening width and depth against kit specs.

Key Things to Know

• Rating is a warning sign – only 1 review at 2.0/5 suggests fit or performance issues. Expect possible vibration, poor cut quality, or blade imbalance.
• Installation is moderate – requires removing the discharge chute, installing baffle plates, and replacing blades. You’ll need a torque wrench (blade bolts: 70-90 ft-lbs typical) and possibly a puller for stubborn spindles.
• Toothed blades dull faster than standard mulching blades, especially on coarse or damp grass. Plan for more frequent sharpening or replacement.
• No warranty support from Cub Cadet – this is a third-party kit. Return policy depends on the seller, not the manufacturer.

Should You Buy It

Only if you already own a 60-inch ZTX series mower and are comfortable troubleshooting fitment issues. The low rating and lack of reviews make this a risk – consider the genuine Cub Cadet mulch kit (742P05516) for guaranteed compatibility and better cut quality, even if it costs more.
