742-05620 742P05620 490-110-C187 (Notched High Lift) Blades - Fits Cub Cadet 60" Deck, Cub Cadet Ultima ZT2-60 KW ZT3-60 KW (3 Pack)

What It Is

This is a 3-pack of OEM-style notched high-lift blades (part numbers 742-05620, 742P05620, 490-110-C187) designed for 60-inch Cub Cadet zero-turn mowers, specifically the Ultima ZT2-60 KW and ZT3-60 KW models. The high-lift design creates stronger airflow to lift grass for a cleaner cut, especially in tall or damp conditions.

Fitment & Compatibility

Before buying, confirm your mower has a 60-inch deck—this 3-pack covers the full deck. Check your blade part number: OEM numbers are 742-05620, 742P05620, or 490-110-C187. These fit Cub Cadet Ultima ZT2-60 KW and ZT3-60 KW models. Measure your existing blade length (should be ~20.5 inches), center hole diameter (~1 inch), and thickness (~0.25 inch). Not compatible with 50-inch decks, older Cub Cadet models, or non-Cub Cadet brands without cross-referencing.

Key Things to Know

• Quality: OEM-grade steel with a durable coating; sharp out of the box. Expect longer life than cheap aftermarket blades but not as thick as premium aftermarket options.
• Installation: Moderate difficulty—requires a socket wrench and torque to 70-80 ft-lbs. Use a blade removal tool or block the blade to prevent spinning. Always disconnect the spark plug first.
• Gotchas: High-lift blades increase engine load and deck vibration; ensure your spindle bearings are in good shape. Notched design reduces clogging in wet grass but may leave a slightly rougher cut on dry, short turf compared to standard blades.
• Mowing tip: For best results, mow at full throttle and avoid cutting more than 1/3 of grass height in a single pass.

Should You Buy It

Yes, if you own a Cub Cadet Ultima ZT2-60 KW or ZT3-60 KW and mow thick, tall, or damp grass regularly. The high-lift design improves bagging and discharge performance. If you only mow dry, manicured lawns on flat terrain, standard blades will suffice and cost less.
