G ravely 00450300 03253800 High Lift Mower Blades Compatible with G ravely Pro-Master 152Z Pro-Turn 152 52 inch Deck Zero Turn Mower (3 Pack)

What It Is

This is a 3-pack of high-lift mower blades designed to replace OEM Gravely part numbers 00450300 and 03253800. They are intended for use on Gravely Pro-Master 152Z and Pro-Turn 152 zero-turn mowers with a 52-inch cutting deck, and are optimized for bagging or side-discharge in tall or wet grass.

Fitment & Compatibility

Before buying, confirm your mower has a 52-inch deck—these blades are 18 inches long and will not fit smaller or larger decks. They are a direct aftermarket replacement for OEM Gravely part numbers 00450300 and 03253800, so they fit Gravely Pro-Master 152Z and Pro-Turn 152 models. Check your existing blade’s center hole diameter (typically 1-inch) and overall length to match. Not compatible with Gravely 60-inch or 48-inch decks. Verify your model year—some older Pro-Turn 152 variants may use a different blade pattern.

Key Things to Know

• High-lift design increases airflow for better bagging and discharge, but can cause more wear on the blade tip and may require more engine power.
• Installation is straightforward—use a torque wrench to tighten to 70-90 ft-lbs (check your manual). No special tools beyond a socket and blade removal tool.
• Balance check recommended—aftermarket blades sometimes vary slightly in weight. Use a blade balancer before installing to avoid vibration.
• Sharpening—these are pre-sharpened but can be re-sharpened 2-3 times before replacement. Avoid over-sharpening as it weakens the blade.

Should You Buy It

If you have a Gravely Pro-Master 152Z or Pro-Turn 152 with a 52-inch deck and need a cost-effective replacement for bagging or heavy grass conditions, this 3-pack is a solid choice. It offers good value compared to OEM blades, but verify your deck size and blade length first to avoid fitment issues.
