Deck Anti-Scalp Wheel Bracket 422478, Compatible with Scag Lawn Mowers SCR42/SCR48/SCR52/SCZ61RD/SCZ72V & More (2-Pack)

What It Is

The Deck Anti-Scalp Wheel Bracket 422478 is a replacement bracket that holds the anti-scalp wheels on Scag zero-turn mowers. It prevents the deck from digging into turf during turns or over uneven ground, reducing scalping damage.

Fitment & Compatibility

Before buying, confirm your Scag model and deck size. This 2-pack fits:

• Scag SCR42, SCR48, SCR52 (Turf Tiger/Super Z)
• Scag SCZ61RD, SCZ72V (Cheetah/Vantage)
• Also compatible with select SCZ, SFC, and SZ models with 48–72 inch decks.

Check your mower’s OEM part number for the original bracket (often 422478 or 422478-XX). Measure the bracket mounting hole spacing—this one uses a 3/8-inch bolt pattern, typically 2.5 inches center-to-center. Verify your wheel stud diameter (usually 1/2 inch) and bracket thickness (about 3/16 inch). Not for older Scag models with different bracket shapes or non-Scag brands.

Key Things to Know

• Quality: Aftermarket bracket, zinc-plated steel. Matches OEM fit but may have slightly thinner metal—fine for residential use, less ideal for heavy commercial abuse.
• Installation: Easy bolt-on with basic hand tools (wrench or socket). No drilling or modification needed if compatible. Torque bolts to 20–25 ft-lbs.
• Gotcha: Anti-scalp wheels sold separately—this is just the bracket. If your wheels are worn, buy new ones (typically 4-inch diameter) to avoid excess wobble.
• Gotcha: Check for bent or cracked deck mounting tabs before installing. If tabs are damaged, the bracket won’t align properly.

Should You Buy It

Buy this if you need a budget-friendly replacement for a Scag deck anti-scalp bracket and your deck tabs are intact. It’s a solid value for homeowners or light commercial use, but professionals may prefer OEM for thicker metal and longer durability.
