LawnRAZOR Blade for Cub Cadet MTD XT2-LX46 XT1-LT46 ZTS1 ZT1 46 46-Inch 742P05510-X 742-05510-X Toothed 2 Pack

What It Is

The LawnRAZOR Blade is a toothed, high-lift replacement blade designed for 46-inch Cub Cadet and MTD lawn tractors. It’s built for mulching, bagging, and general cutting on residential or semi-commercial properties.

Fitment & Compatibility

• Deck size: 46-inch cutting deck only. Measure your deck width to confirm.
• Models: Cub Cadet XT2-LX46, XT1-LT46, ZTS1, ZT1, and MTD equivalents with 46” decks.
• OEM reference: Replaces OEM part numbers 742P05510-X and 742-05510-X. This is an aftermarket blade, not OEM Cub Cadet.
• Measurements: Blade length is ~20.5 inches (center hole to tip), with a 5-point star center hole and 1-inch diameter. Check your spindle pattern – this fits most MTD/Cub Cadet spindles, but verify the star pattern matches your mower.
• What to check: Confirm your mower uses a 5-point star drive (not a 4-point or oval). If you have a different spindle design, this won’t fit.

Key Things to Know

• Toothed design: The serrated edge helps shred grass clippings finer for better mulching, but it wears faster than standard blades on rocky or sandy lawns.
• Installation difficulty: Moderate. Remove the old blade, clean the spindle, and torque to 70–85 ft-lbs. Use a blade removal tool – don’t rely on a socket alone.
• Balance: These blades are pre-balanced, but check with a balancer after sharpening. An unbalanced blade causes vibration and cuts unevenly.
• Gotcha: The toothed edge can catch on thick grass or wet clumps, potentially bogging the engine if you mow too fast. Keep ground speed moderate.

Should You Buy It

If you have a 46-inch Cub Cadet or MTD tractor and want aggressive mulching or bagging performance, the LawnRAZOR is a solid aftermarket upgrade. It’s not for decks smaller than 46 inches or non-Cub Cadet spindles. For $51.95, you get two blades that cut well but may wear faster than OEM on rough terrain.
