8TEN LawnRAZOR Blade for Cub Cadet Ultima ZT2 60 Inch Deck 742-05620 742P05620 490-110-C187 (Notched High Lift) 3 Pack

What It Is

The 8TEN LawnRAZOR Blade is a notched high-lift replacement blade designed for Cub Cadet Ultima ZT2 zero-turn mowers with a 60-inch deck. It’s built for heavy-duty cutting and improved grass discharge, making it suitable for residential and commercial use.

Fitment & Compatibility

Before buying, confirm your mower deck is exactly 60 inches—this blade won’t fit smaller or larger decks. Check your OEM part number: this set replaces Cub Cadet 742-05620, 742P05620, and 490-110-C187. Measure your blade length (should match 20.5 inches) and center hole diameter (must be 1 inch). Verify the notch pattern matches your spindle—Cub Cadet Ultima ZT2 models with 60-inch decks use this style. If you have a different Cub Cadet series or deck size, it won’t fit.

Key Things to Buy

• Quality: 8TEN LawnRAZOR blades are heat-treated and hardened for durability, with a notched high-lift design that improves grass lift and mulching. They’re a solid aftermarket alternative to OEM.
• Installation: Moderate difficulty. You’ll need a socket wrench and torque wrench to tighten the center bolt to 70-90 ft-lbs. Ensure the blade is oriented with the lift wing facing up toward the deck.
• Common gotcha: The notched design can cause more vibration if the blade is unbalanced. Always balance new blades before installing—use a balancer tool or a nail in a wall.
• Pack size: This is a 3-pack, enough for a full deck replacement. Check your mower uses three blades (most 60-inch Cub Cadet decks do).

Should You Buy It

Yes, if you own a Cub Cadet Ultima ZT2 with a 60-inch deck and want a reliable, high-performance aftermarket blade that matches OEM specs at a lower price. The high lift improves clipping discharge and bagging, making it ideal for thick or wet grass. Avoid if you need a low-lift or mulching-only blade.
