2 Pack 422478 Deck Anti-Scalp Wheel Bracket & Roller Kit for Scag Riding Mowers SMST SCR4 SVRII STT52-22KA SFZ52 SFZP52 SWZT61and More, w/ 481632 Deck Wheel, 04003-26 10225 Bolt and 04021-05 Nut

What It Is

This is a 2-pack of deck anti-scalp wheel brackets and rollers designed for Scag riding mowers. It prevents the deck from scalping (scalping the grass) on uneven terrain by keeping the deck level and reducing turf damage.

Fitment & Compatibility

Before buying, check your Scag model and deck size. This kit fits Scag SMST, SCR4, SVRII, STT52-22KA, SFZ52, SFZP52, and SWZT61 models (and others with similar deck brackets). Measure your deck’s wheel bracket mounting hole spacing—this kit uses a bolt (04003-26) and nut (04021-05) that fit standard Scag deck holes. It’s an aftermarket replacement for OEM part 422478, so verify your existing bracket part number. Not for zero-turn mowers with non-standard deck mounts or non-Scag brands without adapter kits.

Key Things to Know

• Build quality: The bracket is stamped steel, not cast; it’s durable but can bend under heavy loads. The roller is hard plastic—replace if cracked.
• Installation: Moderate difficulty. You’ll need a wrench and possibly a socket. Remove old bracket, bolt on new one, then attach the wheel/roller. Ensure the roller spins freely after tightening.
• Common gotcha: The included bolts may be too short for thicker deck frames. Measure your deck thickness; if over 1/4", buy longer 5/16" bolts separately.
• Fitment nuance: Some Scag models (e.g., STT52) have offset brackets; this kit is straight. Check your original bracket’s angle before ordering.

Should You Buy It

Buy this if you have a compatible Scag mower and need a direct, budget-friendly replacement for worn or missing anti-scalp brackets. It’s a solid value for the price, but skip it if your deck requires angled brackets or thicker bolts—then buy OEM or measure carefully.
