JSXDNWYJ High-Lift Mower Blades for Gravely 52-inch Deck — 3-Pack, Hardened Steel & Green Rust-Resistant Finish

JSXDNWYJ high-lift lawn mower blades are a 3-pack of heavy-duty replacement blades engineered to fit 52" Gravely decks and restore cutting performance on Pro-Master and Pro-Turn zero-turn mowers.

These blades are designed as direct-fit replacements for Gravely OEM 00450300, delivering the lift profile and dimensions needed to reproduce factory airflow and bagging performance on 52-inch decks. Built from hardened steel with a protective green finish, each blade balances durability and resistance to surface corrosion for season-long reliability. Below you’ll find straightforward answers to common buyer questions so you can decide if these blades meet your mower maintenance needs.

Will these blades fit my Gravely 52-inch deck?

If your machine specifies Gravely OEM number 00450300 or is one of the listed models with a 52" deck, these blades are made to match the same hole pattern and length so installation is straightforward. Confirming the center hole size and overall length before purchase prevents compatibility issues.

• Replaces OEM number: Gravely 00450300
• Compatible models: Rapid XZ, Pro-Master 152Z, Pro-Master 152Z XDZ, Pro-Master 152i, Pro-Turn 152
• Deck size: 52-inch mower decks
• Center hole: 5/8" (verify your spindle bolt size)

What are the blade dimensions and construction?

Each blade measures 18 inches end-to-end with a working width of 2-1/2 inches and a thickness of 0.248 inches, giving a robust profile suited to commercial-style cutting decks. The blades are stamped and heat-treated from steel, then coated with a green paint layer to reduce surface rust and help preserve the edge between sharpenings.

• Length: 18 in; Width: 2.5 in; Thickness: 0.248 in
• Material: high-quality hardened steel
• Finish: green protective paint for corrosion resistance
• Center hole: 5/8" for common spindle compatibility

How do these blades affect cutting performance and maintenance?

The high-lift design promotes stronger airflow beneath the deck, improving clippings lift for cleaner cuts and better bagging where applicable. A properly balanced blade reduces vibration and uneven wear, and the durable steel construction maintains edge life so you sharpen less often under normal use.

• High-lift profile increases suction for cleaner cut and bagging
• Hardened steel offers longer edge life versus soft stamped blades
• Painted surface helps prevent rust and simplifies cleanup
• Sold as a 3-pack to replace all blades on a typical three-blade 52" deck

What support or warranty comes with the blades?

JSXDNWYJ offers quality control on every blade and provides after-sales support to resolve fitment or satisfaction issues quickly. If you encounter a problem, contact the seller to request a replacement or refund according to their policy.

• Strict quality checks during production
• After-sales support available for replacements or refunds

Who is this for: These blades are intended for owners or service technicians who maintain Gravely Rapid XZ, Pro-Master, or Pro-Turn zero-turn mowers with a 52" deck and need a reliable, OEM-equivalent blade replacement. They suit commercial landscapers and homeowners with heavy-duty mowing needs who want direct-fit replacements that restore factory cutting performance without modifying spindles or deck hardware.
