HQPASFY 422478 Deck Anti-Scalp Wheel Bracket & 481632 Roller Kit, Compatible with Scag Mowers SMST/SMWC/STT52/STT61A/SFZ52/SFZP52/SWZT61/SZL48/SCR42/SCZ61RD/STC40/STC48V & More (4 Sets)

What It Is

This is a 4-set kit combining anti-scalp wheel brackets (OEM 422478) and roller kits (OEM 481632) for Scag zero-turn and walk-behind mowers. It prevents scalping on uneven terrain by keeping the deck level and stable, reducing damage to turf and the deck itself.

Fitment & Compatibility

Before buying, confirm your Scag model matches one of these: SMST, SMWC, STT52, STT61A, SFZ52, SFZP52, SWZT61, SZL48, SCR42, SCZ61RD, STC40, STC48V. Also check deck size (42"–61") and existing bracket/roller bolt patterns. These are aftermarket replacements for OEM parts, so measure your current bracket width and roller diameter (typically 4" wheels and 2-3/8" rollers). If your mower uses a different bracket design (e.g., welded vs. bolt-on), this kit won’t fit. Verify you need four sets—some decks only use two.

Key Things to Know

• Installation: Moderate difficulty. You’ll need a wrench and possibly a socket set; brackets bolt to the deck, rollers attach with pins. No drilling required if holes align.
• Quality: Steel brackets and rubber rollers. Some users report the rollers wear faster than OEM, especially on rough ground or gravel. Check for burrs on bracket edges before install.
• Common gotcha: The anti-scalp wheels may not clear low-profile decks (e.g., 42" models) without adjusting deck height. If your deck sits very low, the wheels might drag.
• Hardware: Kit includes bolts and pins, but not always lock washers. Use thread locker if you mow on bumpy terrain to prevent loosening.

Should You Buy It

Buy this if you own a compatible Scag mower and want an affordable multi-set replacement for worn or missing anti-scalp/roller components. It’s a solid value for the price, but skip it if you need exact OEM durability for heavy commercial use—aftermarket rollers may need replacement sooner. For residential or light commercial mowing, it’s a good fit.
