If your 60-inch Cub Cadet deck is producing uneven cuts, scalping, or vibration, replacing worn or damaged blades with the correct OEM parts is the fastest way to recover factory-level performance. These 742P05516 replacement blades are manufactured to Cub Cadet specifications and intended to fit a range of Pro Z and ZTX-series 60" FAB Ultima decks. The set of three gives you a complete replacement for a 60-inch three-blade deck in one purchase.

Which mowers will these blades fit?

These blades are made to match Cub Cadet's original equipment fit and mounting pattern for many 60-inch zero-turn models. They are compatible with Pro Z and multiple ZTX and ZTXS series machines that use a 60" Fab Ultima deck platform. Always double-check your mower’s owner's manual or current blade part number to confirm fit before installing.

How do these blades improve cutting performance?

New blades restore cutting efficiency by re-establishing sharp, consistent edges and the correct blade pitch for airflow under the deck. This helps produce cleaner grass clippings, reduce tearing, and promote even mulch or discharge patterns.

• Sharp, factory-spec edge for crisp cuts
• Balanced construction to minimize vibration
• Correct blade geometry to maintain proper deck airflow

What should I check before installation?

Confirm blade compatibility with your mower model and inspect spindle hardware and deck condition before mounting new blades. Replace worn bolts, washers, and blade adapters as needed and torque to the manufacturer’s specification to ensure safety and performance.

• Verify part number 742P05516 against your manual
• Inspect spindle, belts, and mounting hardware for wear
• Use correct torque values and safety procedures during installation

How long can I expect the blades to last and how should I maintain them?

Blade life varies with grass type, ground conditions, and usage frequency; regular sharpening and avoiding hard impacts extends service life. Remove buildup after each use, sharpen when edges dull, and replace blades if bent or chipped to maintain cutting quality and safety.

• Sharpen when cutting quality declines or every 20–25 hours of use
• Inspect for nicks, bends, and balance after any impact
• Replace all three blades together for balanced operation
