Ariens 3 OEM High Lift Mower Blades Ariens Gravely Pro-Turn 152 w/ 52'' Deck 00450300

What It Is

This is a set of three OEM (Original Equipment Manufacturer) high-lift mower blades designed for Ariens and Gravely Pro-Turn 152 mowers with a 52-inch deck. High-lift blades create stronger airflow for superior grass clipping discharge and bagging performance, making them ideal for tall or wet grass conditions.

Fitment & Compatibility

• Deck size: 52-inch cutting deck only. Measure your deck width from blade tip to blade tip.
• Models: Ariens Pro-Turn 152 and Gravely Pro-Turn 152 with 52-inch deck. Not for 48-inch or 60-inch decks.
• OEM part number: 00450300. This is a direct OEM replacement, so it matches factory specs exactly. Aftermarket blades may differ in thickness, balance, or hole alignment.
• Blade measurements: Each blade is approximately 18 inches long with a 1-inch center hole and 5/8-inch spindle hole. Verify your spindle shaft size before ordering.
• Check your deck’s blade retention system: These use a standard center bolt. If your deck uses a different retention method (e.g., pin or clip), these won’t fit.

Key Things to Know

• Installation difficulty: Moderate. You’ll need a socket wrench and torque wrench (recommended torque: 70-90 ft-lbs). Lift the mower safely and block the deck.
• Sharpness: These come sharp but not razor-edged. They’ll cut well for several hours before needing sharpening. Dull blades tear grass, leading to brown tips.
• Balance: OEM blades are factory-balanced. If you sharpen them, always re-balance to avoid vibration that can damage the spindle.
• High-lift trade-off: Better discharge and bagging, but they require more engine power and may clog in very dry, dusty conditions. Not ideal for mulching.

Should You Buy It

Buy these if you have an Ariens or Gravely Pro-Turn 152 with a 52-inch deck and you frequently bag clippings or cut tall/wet grass. The OEM fit ensures no guesswork, and the high-lift design maximizes airflow. Skip them if you primarily mulch or cut in dry, short grass—a standard or mulching blade would be more efficient.
