Ariens 3-Pack OEM 18-inch Hi‑Lift Mower Blades for 52-inch Pro-Turn 152 — Gravely 00450300, Factory-Balanced

High-lift replacement blades engineered to restore the cutting performance and bagging efficiency of 52" Pro-Turn decks — three OEM Gravely 00450300 18" hi-lift blades in one kit.

This 3-pack supplies genuine OEM Gravely 00450300 18-inch hi-lift blades that are compatible with Ariens and Gravely Pro-Turn 152 riding mowers with a 52" deck. Fresh blades return crisp cutting, improved clippings lift, and better material movement inside the deck, which matters for mowing speed, bagging, and mulching consistency. Each blade is manufactured to factory specifications so mounting, balance, and deck clearance match the original equipment.

How will these blades change mowing performance?

Hi-lift blades are shaped to create stronger upward airflow under the deck. That lift moves clippings more efficiently into a bagger or through the discharge, reducing clumping and improving finish quality at higher grass volumes.

• Stronger suction for cleaner bagging and collection
• Smoother discharge, reducing clumps on the lawn
• Factory-balanced shape to minimize vibration
• Designed for 52" deck geometry to maintain deck airflow

Are these the correct blades for my Ariens or Gravely Pro-Turn 152?

Yes — these are the OEM Gravely part number 00450300 hi-lift blades specified for Pro-Turn 152 models with a 52" deck. They match the original blade length, mounting hole pattern, and lift profile used on those machines, so installation is straightforward.

• 18" blade length matching the factory blade
• OEM Gravely part #00450300 for exact compatibility
• Ships as a set of three for full deck replacement
• Fits Pro-Turn 100/200/600 families and Pro-Walk variants as listed by OEM

What are the installation and maintenance considerations?

Installing these blades requires basic mower maintenance skills: safely support the machine, remove blade bolts, swap blades, and torque to the manufacturer’s specification. Regularly inspect for nicks and balance, and replace the set when blade wear affects cut quality or balance.

• Follow mower manual for lift and torque specs
• Replace all three blades at once for balanced operation
• Sharpen blades periodically to maintain cutting performance
• Inspect for bent or cracked metal after impacts

Why choose genuine OEM Gravely blades instead of aftermarket copies?

OEM blades are manufactured to original tolerances for length, balance, and hole pattern so they perform like the factory-installed parts. That reduces the risk of vibration, poor fit, or compromised deck airflow that can arise from mismatched aftermarket blades.

• Exact factory spec reduces fitment issues
• Consistent balance lowers vibration and wear
• Preserves deck airflow intended by the manufacturer
• Simpler warranty and parts traceability with OEM number

Who is this for: This three-blade OEM kit is aimed at owners of Ariens and Gravely Pro-Turn 152 (and compatible Pro-Turn/Pro-QXT/Pro-Walk) mowers with a 52" deck who need a direct-fit replacement to restore factory cutting and collection performance. It’s ideal for landscapers, grounds crews, and homeowners who demand consistent bagging and a smooth, balanced ride from their mower deck.
