2PK Genuine OEM Wright Anti Scalp Roller Deck Wheel 72490003 72490002 Aero Core

What It Is

This 2-pack of genuine OEM Wright anti-scalp roller deck wheels (part numbers 72490003 and 72490002) prevents the mower deck from scalping uneven terrain, protecting the blade tips and reducing turf damage on Wright Aero Core zero-turn mowers.

Fitment & Compatibility

Before buying, confirm you need the 4.5-inch roller wheel diameter (measure your existing wheel’s outer diameter). These fit Wright Aero Core decks—specifically models like the Aero Core 48, 52, and 61, plus some Stander and Sentar models with the same anti-scalp roller setup. Check your deck’s mounting bracket: these use a 3/8-inch shoulder bolt (not included) and a 1-inch axle hole. If your mower uses a different bolt size or a non-OEM bracket, these won’t mount securely. Always verify your serial number against Wright’s parts diagram—these are not universal for all Wright ZTRs or other brands.

Key Things to Know

• Quality: Genuine OEM Wright parts—exact fit, no modification needed. The nylon roller is durable but not impact-resistant; avoid hitting curbs or rocks.
• Installation: Easy swap—remove the old roller’s bolt, slide the new wheel on, and retighten (torque to 30-40 ft-lbs). No special tools required.
• Common gotcha: The wheel’s bushing is pre-lubricated; don’t add grease—it attracts debris. Also, check the bracket for wear; a bent bracket will cause premature roller failure.
• Pack size: Two wheels per pack—enough for one axle set (front or rear) on most Aero Core decks. If you need all four, buy two packs.

Should You Buy It

Buy this if you own a Wright Aero Core ZTR and need a direct, no-guesswork replacement for worn or missing anti-scalp rollers. It’s the right choice for maintaining factory-grade turf protection and avoiding scalping on bumpy lawns. Skip it if your deck uses a different roller size or bracket design—measure twice first.
