Parts 4 Outdoor After Market 6Pk Anti-Scalp Roller kit for Gravely Ariens 03905900 00473700 00473800 06225900

What It Is

This is a set of six aftermarket anti-scalp rollers designed to replace worn or broken originals on zero-turn mowers with stamped-steel decks, specifically for Gravely and Ariens models using OEM part numbers 03905900, 00473700, 00473800, and 06225900. They prevent the deck from digging into turf during turns or on uneven ground.

Fitment & Compatibility

Before buying, confirm your mower’s deck size is 48–60 inches (common for these brands) and that the roller mounting holes match a 5/16-inch bolt pattern. These replace OEM rollers on Gravely ZT, ZTH, and Pro-Turn series and Ariens Ikon, Edge, and Zoom models from the mid-2010s onward. Measure your existing roller’s outside diameter (these are ~4 inches) and spindle length (~1.5 inches) to ensure they match. They do not fit fabricated decks or older models with different bolt spacing—check your deck’s stamped steel construction first.

Key Things to Know

• Quality vs OEM: These are hard plastic, not urethane—they’ll wear faster on abrasive surfaces like concrete or gravel, but work fine on grass. Expect 1–2 seasons of residential use.
• Installation: Simple bolt-on job with basic hand tools (wrench or socket set). No drilling or modification needed if fitment is correct. Anti-seize on bolts helps future removal.
• Common Gotcha: The included hardware may be slightly shorter than OEM—check that bolts fully engage the lock nut without bottoming out. Add washers if needed.
• Pack Contents: You get six rollers (enough for a full deck replacement) with mounting bolts and nuts. Some users report missing hardware—verify upon arrival.

Should You Buy It

If you need a cheap, fast fix for scalping on a stamped-deck Gravely or Ariens zero-turn and don’t mind replacing rollers every couple years, this kit delivers solid value. Avoid if you have a fabricated deck, want maximum durability on hard surfaces, or need exact OEM fit without any fuss.
