• Exact fit for Gravely OEM 00450300 replacements
• Designed for 52" mower decks on listed models
• 5/8" center hole and standard thickness for secure mounting
• Install using factory hardware — no drilling or grinding required

What cutting performance can I expect with high-lift LawnRAZOR blades?

High-lift blades generate stronger suction beneath the deck, which lifts grass upright for a cleaner, more even cut and better material ejection. That improved airflow helps when bagging, mulching, or side-discharging, especially in thicker or slightly damp turf.

• Sharper, more consistent cut quality across the 52" deck
• Improved clippings evacuation for cleaner decks and bags
• High-lift profile maintains lift even as the edge wears
• 18" length and 2 1/2" width for balanced performance and coverage

How durable are these replacement blades and what are their specs?

8TEN LawnRAZOR blades are stamped and finished to the OEM-like dimensions and tempered to resist bending and premature wear under normal mowing conditions. They are built with a 0.025" thickness that balances flexibility and strength for commercial-style use on residential and light-commercial mowers.

• Blade length: 18"; width: 2 1/2"
• Thickness: 0.025 inch for consistent edge retention
• 5/8" center hole for factory spindle compatibility
• Sold as a convenient 3-pack to replace a full deck set or keep spares handy

How easy is installation and routine maintenance?

Installation is a straightforward process: raise and support the mower, remove the old blades with the correct wrench, and torque the new blades to the manufacturer’s recommended specification. Routine maintenance is limited to periodic sharpening and checking mounting hardware for secure fitment.

• Direct replacement — no modification required
• Sharpen as needed; replace when worn or damaged
• Check blade bolts after first few hours of operation
• Keep deck clean to prolong blade life and performance

Who is this for? Lawn care professionals, landscapers, and homeowners who own Gravely Rapid XZ, Pro-Master 152Z/152Z XDZ/152i, or Pro-Turn 152 zero-turn mowers with 52" decks and need an OEM-compatible high-lift blade replacement will find the 8TEN LawnRAZOR 3-pack an economical and reliable option. If you want a direct-fit blade that restores airflow and cutting consistency without modifying your deck, this 3-pack provides immediate spares for routine maintenance or mid-season swaps.
