Ariens Gravely 00450300 Mower Blades Pro-Turn 152 w/ 52'' Deck Set of 6 OEM

What It Is

This is a set of six OEM replacement blades designed for the Ariens Gravely Pro-Turn 152 with a 52-inch cutting deck. It includes all three pairs (6 blades total) needed for a full deck change, intended for commercial-grade mowing on turf and heavy grass.

Fitment & Compatibility

Before buying, confirm your mower is an Ariens or Gravely Pro-Turn 152 with a 52-inch deck only—not 48", 60", or other sizes. Check that your existing blades are the same length (typically 18 inches) and have a 1-inch center hole with a 5-point star drive. This is an OEM part (00450300), so it fits directly without modification on listed models. Verify your deck spindle count: this set covers all 6 blades (3 pairs) for a 3-spindle deck. Aftermarket blades may differ in thickness or hole shape—measure your current blades if unsure.

Key Things to Know

• Quality: OEM Ariens/Gravely blades are heat-treated for durability and balanced from the factory; aftermarket sets may be thinner or less consistent.
• Installation: Moderate difficulty—requires removing the deck or accessing spindles from underneath. Use a torque wrench to tighten nuts to 70-90 ft-lbs; never over-torque.
• Common gotcha: The star-drive center hole is specific—don’t force a round-hole blade onto a star spindle. Also, blades are directional; ensure the lifting edge faces up toward the deck.
• Replacement frequency: Swap every 25-50 hours of mowing or sooner if you hit debris—dull blades tear grass and strain the engine.

Should You Buy It

If you own a Pro-Turn 152 with a 52" deck and want reliable, factory-spec performance, this set is a no-brainer—it’s exactly what the mower was designed for. Skip if you have a different deck size, prefer cheaper aftermarket options, or only need individual blades rather than a full set.
