Wright Anti Scalp Roller Deck Wheel Deck Mowers / 2 Pack / 72490003, 72490002

What It Is

This is a genuine Wright anti-scalp roller deck wheel set (2-pack) designed to prevent the mower deck from scalping uneven turf on zero-turn mowers. It’s intended for Wright commercial mowers with stamped or fabricated decks that use roller-style anti-scalp wheels.

Fitment & Compatibility

• Direct OEM replacement for Wright part numbers 72490003 and 72490002 (each pack includes one of each).
• Fits Wright models: Stander, Sentar, ZK, ZTH, and ZTR series with 48”, 52”, 54”, 60”, or 72” decks that use roller-type anti-scalp wheels.
• Check your current wheel’s bolt pattern: These use a 5/16” bolt with a 2.5” outer diameter wheel. Measure your existing wheel’s bolt hole spacing and shaft diameter to confirm.
• Not compatible with Wright models that use solid rubber or flat idler-style wheels (e.g., some older ZTRs with 4-bolt hubs). If your anti-scalp wheel has a steel hub with a grease fitting, these won’t fit.
• Aftermarket note: Only buy if you need the exact Wright OEM spec—generic “universal” rollers are often 1/8” thinner and may wear faster.

Key Things to Know

• No tools included: You’ll need a 5/16” socket and wrench to swap them. Anti-scalp wheels are usually held by a single bolt and lock nut.
• Lubrication tip: Apply a drop of light oil to the roller bearing before installing to reduce friction and extend life.
• Common gotcha: The left and right wheels are identical in this set—no need to worry about orientation.
• Wear indicator: If your current wheel wobbles or has flat spots, replace immediately to avoid deck damage.

Should You Buy It

Buy this if you own a Wright zero-turn with a roller-style anti-scalp system and need a direct OEM replacement that matches factory quality. It’s a no-fuss swap for maintaining clean, even cuts on uneven terrain. Skip it if you have a different brand or a Wright with solid rubber wheels.
