Mr Mower Parts 54" Ultra High-Lift Mower Blade Set for Craftsman 742-05086 — Diamond Hole S-Spindle, .158" Thick

These are replacement ultra high-lift blade set for 54-inch cutting decks engineered to fit "S" style spindle shafts on select Craftsman, Cub Cadet, MTD and Troy-Bilt machines.

If your 54" deck is leaving clumps, not discharging cleanly, or the blades are nicked and worn, the Mr Mower Parts CMXGZAM110194 Ultra High-Lift Blade Set restores lift, airflow and cutting performance. Each blade is formed with a diamond-shaped center hole to match "S" shaped spindle shafts and built to the OEM-compatible dimensions: 18 5/8" overall length and .158" thickness. These blades are a direct-fit replacement for Craftsman part numbers like 742-05086 / 742P05086 and work across many Cub Cadet, MTD and Troy-Bilt decks that use the same blade style.

Will these blades fit my Craftsman or Cub Cadet 54" deck?

They are designed specifically for decks that use the "S" style spindle and a diamond-shaped center hole. Confirm your current blade’s hole shape and overall length to ensure compatibility.

• Blade length: 18 5/8" center-to-tip standard for 54" decks
• Center hole: diamond shape to match "S" style spindles
• Thickness: .158" to match OEM mounting hardware
• Confirmed replacement for Craftsman 742-05086 / 742P05086

How does the ultra high-lift profile affect cutting and discharge?

The ultra high-lift contour increases upward airflow under the deck so clippings are lifted and ejected more effectively, producing a cleaner cut and better side discharge or mulching performance where applicable.

• Stronger suction lifts grass blades for an even cut
• Improved discharge reduces clumping on the lawn
• Better bagging performance if your machine uses a catcher
• Helps maintain consistent deck vacuum across dense turf

Are these blades durable and easy to install?

Manufactured from high-grade steel with precise hole and length dimensions, these blades are built to resist wear and retain edge geometry longer than heavily damaged OEM blades. Installation follows the same steps as the original blades—use proper torque and orientation.

• Durable steel construction for extended service life
• Pre-formed holes and edges for straightforward replacement
• Replace in matched sets to preserve deck balance
• Use manufacturer torque specs and safety procedures

Which specific models are compatible with this blade set?

These blades cover many Craftsman, Cub Cadet, MTD and Troy-Bilt models that ship with the same blade type and center-hole geometry. Always cross-check part numbers and blade measurements before ordering.

• Fits Craftsman models like those using part 742-05086 / 742P05086
• Compatible with numerous Cub Cadet 54" tractor decks
• Suitable for a range of MTD and Troy-Bilt 54" mower decks
