CUB CADET Xtreme Mulching Blade Set for 60" Ultima Deck — 490-110-C188 OEM 3-Blade, Balanced Mulch Performance

These are the OEM CUB CADET 490-110-C188 Xtreme mulching blades, a three-blade set engineered to restore mulching performance on 60" Cub Cadet Ultima decks.

If your ZT2-60, ZT3-60 or ZTS2-60 Fab ride-on is leaving clumps, producing uneven discharge, or losing cut quality, replacing worn or damaged blades with the factory-replacement 490-110-C188 set brings back the original cutting and mulching geometry. This listing references the current OEM number (490-110-C188) and replaces the prior MPN 742P05620 / 742-05620. Installing correct-fit blades helps maintain deck balance, reduce vibration, and improve grass clipping distribution when used with a compatible 60" deck.

How do these blades improve mulching compared to generic replacements?

These Xtreme mulching blades are manufactured to Cub Cadet's original specifications so the cutting edge profile and lift characteristics match the 60" Ultima deck design. That means finer re-cutting of clippings and more even circulation inside the deck, which helps produce a consistent finish.

• Factory OEM geometry for intended lift and airflow
• Balanced three-blade set to reduce vibration
• Sharper cutting angle tuned for finer mulching
• Direct fitment avoids modification or adapters

Which Cub Cadet models and decks are these blades compatible with?

The 490-110-C188 Xtreme mulching blade set fits specific Cub Cadet Ultima 60" fabricator decks. Confirm compatibility using your mower’s owner manual before purchase to ensure correct installation and safety.

• Compatible models: ZT2-60 Fab, ZT3-60 Fab, ZTS2-60 Fab
• Designed for 60" Ultima cutting decks
• Replaces prior part numbers 742P05620 and 742-05620
• OEM part number: 490-110-C188

What comes in the package and what should I check before installation?

This purchase includes a set of three blades sized for a 60" deck. Before installing, park the mower on level ground, disconnect the spark plug, and inspect blade mounts and hardware for wear so the new blades seat properly and remain balanced.

• Includes three OEM Xtreme mulching blades
• Check blade bolts, spindles, and deck for damage
• Use manufacturer torque specs when tightening bolts
• Re-balance blades if vibration persists after install

How long will these blades maintain cutting performance?

Life depends on terrain, frequency of use, and contact with obstacles. Using OEM-quality blades preserves cutting geometry longer than generic blades, but inspect edges regularly and replace when nicks or significant dulling appear.

• Typical lifespan varies with mowing conditions
• Resharpen if only slightly dull; replace if bent or nicked
• OEM design helps delay premature wear under normal use
• Keep blade bolts tight and replace damaged hardware

Who is this for: This three-blade Xtreme mulching set is intended for owners of Cub Cadet Ultima 60" deck tractors—specifically the ZT2-60, ZT3-60 and ZTS2-60 fabricator models—who want a direct OEM replacement to restore factory mulching performance. If you prefer original-spec parts for fit, balance, and consistent cut quality, this blade set is the correct OEM choice. Always verify compatibility with your mower’s owner manual before ordering to ensure a safe and correct installation.
