JXJKCZ 2-Pack Ultra High-Lift Mower Blades for 42" Deck - 21-1/4" Diamond 7/8" Center, Heat-Treated

These are two high-lift replacement mower blades from JXJKCZ engineered to fit 42-inch Cub Cadet/MTD decks and replace OEM 742-05177, 742P05177, and 742P05528.

When your lawn mower's cutting performance drops or the deck no longer throws clippings cleanly, replacing worn blades restores lift, bagging and mulching efficiency. The JXJKCZ 2-pack offers full-length, ultra high-lift blades made to the same center diamond hole and dimensions as common OEM replacements so they install without modification. Built from heat-treated steel and finished for corrosion resistance, these blades are made to bring consistent cutting results for residential riders and garden tractors.

Will these blades fit my mower model?

These blades are designed for a wide range of 42-inch decks from Cub Cadet, MTD, Craftsman and Troy-Bilt. Check your mower’s deck size and the OEM part numbers or the diamond 7/8" center hole and blade length to confirm compatibility.

How do these high-lift blades affect cutting and collection?

High-lift blades are shaped to generate stronger upward airflow inside the deck, improving grass lift for an even cut and better bagging performance. They help move clippings through the chute and into a bagger or mulcher housing more efficiently than low-lift designs.

• Ultra high-lift profile increases suction for cleaner discharge
• Promotes consistent clipping transport to the bag or mulch chamber
• Leaves a more uniform cut on dense or tall grass

What are the physical specifications and material quality?

Each blade in this JXJKCZ pair measures 21 1/4 inches end-to-end with a 2 3/8 inch cutting width and a diamond 7/8" center hole to match OEM mounting. They are stamped and heat-treated for strength, then finished to resist rust and wear under normal homeowner use.

• Length: 21 1/4"; width: 2 3/8"; center hole: diamond 7/8"
• Type: high-lift blades for improved airflow
• Manufactured with heat treatment for longer life

How easy is installation and what maintenance do these blades need?

Installation is straightforward for anyone comfortable with basic mower maintenance: disconnect the spark plug, raise the deck, remove the old blades and fasten the new ones using the original hardware. Regular inspection and sharpening as needed keep cutting performance optimal and extend blade life.

• Simple bolt-on replacement using existing spindle hardware
• Recommended: balance and torque mounting bolts to manufacturer specs
• Sharpen and check for nicks after every season or heavy use
