Lawn Mower Blades with 52 inch Deck Fits for 00273100 03399704 038-3000-00 for Gravely Pro-Master 152Z 152i Ariens PM252H Zoom 2252 2352 2452 Max Zoom 2552, 3 PCS

What It Is

This is a set of three aftermarket lawn mower blades designed for 52-inch cutting decks, specifically engineered to fit Gravely Pro-Master and Ariens Zoom series zero-turn mowers. These blades replace OEM part numbers 00273100, 03399704, and 038-3000-00, making them suitable for heavy-duty residential and commercial mowing tasks.

Fitment & Compatibility

Before buying, confirm your mower has a 52-inch deck—this set will not work on smaller or larger decks. The blades are direct replacements for Gravely Pro-Master 152Z, 152i, and Ariens Zoom models including PM252H, Zoom 2252, 2352, 2452, and Max Zoom 2552. Check your current blade’s length, width, center hole diameter, and thickness (typically 0.25–0.313 inches for these models). Also verify the sail orientation (upward or downward) to match airflow direction. OEM part cross-references: Gravely 00273100, Ariens 03399704, and 038-3000-00. If your mower uses a different spindle pattern or blade offset, these may not fit.

Key Things to Know

• Quality: Aftermarket blades at this price point are often made from 10-gauge or 8-gauge steel—good for residential use but may dull faster than OEM in heavy commercial cutting or rocky terrain.
• Installation difficulty: Moderate. You’ll need a socket wrench, torque wrench (recommended 70–90 ft-lbs), and a blade removal tool or block of wood to prevent spinning. Always disconnect the spark plug first.
• Common gotchas: The 3-blade set requires careful alignment—mixing up left/right blades or using incorrect sail orientation can cause poor cut quality or vibration. Check that the center hole diameter matches your spindle (typically 5/8-inch or 7/8-inch on these models).
• Balance: Aftermarket blades may need balancing before installation to avoid vibration and spindle wear. Use a blade balancer tool.

Should You Buy It

If you own a compatible Gravely or Ariens 52-inch zero-turn mower and need an affordable replacement for light-to-moderate mowing (lawn, not rough terrain or commercial daily use), this set offers good value. However, for heavy commercial use or abrasive conditions, consider OEM or premium aftermarket blades with thicker steel or hardened edges.
