8TEN LawnRAZOR Mower Blade Set for Gravely Pro-Master 152Z Pro-Turn 152 52 inch Deck Zero Turn 00450300 (High Lift)

What It Is

This is a set of three high-lift replacement blades for 52-inch cutting decks on Gravely Pro-Master 152 and Pro-Turn 152 zero-turn mowers. Designed for heavy lifting and improved discharge in thick or wet grass, they’re aftermarket equivalents to OEM part 00450300.

Fitment & Compatibility

Check before buying:

• Deck size: Must be exactly 52 inches—this set includes three blades, not two or four.
• Model compatibility: Fits Gravely Pro-Master 152Z, Pro-Turn 152, and any 52-inch deck using OEM 00450300 blades. Not for other Gravely decks (e.g., 50-inch or 60-inch).
• Measurements: Each blade is 17.5 inches long, 2.5 inches wide, with a 0.203-inch thickness and a 5/8-inch center hole. Verify your current blade matches these dimensions.
• OEM vs aftermarket: LawnRAZOR is a third-party brand. If your deck uses a different OEM blade number (like 00450300 for Gravely), this is a direct fit. For other brands (e.g., Ariens, Husqvarna), check if they use the same OEM part—don’t assume.

Key Things to Know

• Quality: Heat-treated steel with a painted finish. Rated 4.6/5—users report good durability and sharpness out of the box, but some note edge dulling faster than OEM in sandy soil.
• Installation: Straightforward swap if you’re comfortable with a socket and torque wrench. Use a blade removal tool for safety. Torque bolts to 45-55 ft-lbs (check your manual).
• Gotchas: High-lift blades increase engine load and may reduce fuel efficiency slightly. They also throw debris more aggressively—wear eye protection and clear the area. Not ideal for bagging if your deck lacks a high-lift chute.
• Balance: Some users recommend checking blade balance before install; minor imbalances can cause vibration.

Should You Buy It

This is a solid value for Gravely Pro-Master or Pro-Turn owners with a 52-inch deck who want better cutting performance in tall, thick grass without paying OEM prices. Avoid if you need standard-lift blades for mulching or bagging, or if your deck isn’t a 52-inch Gravely.
