Scag Anti-scalp Wheel Part # 481632

What It Is

The Scag Anti-scalp Wheel Part # 481632 is a replacement gauge wheel that prevents the mower deck from scalping (digging into) turf on uneven terrain. It’s designed for Scag zero-turn mowers with 48- to 72-inch decks, including the Cheetah, Tiger Cat, and Wildcat series.

Fitment & Compatibility

Before buying, check these three things:

• Deck size and model: Fits Scag decks from 48" to 72". Common compatible models: Cheetah (2005+), Tiger Cat (2007+), Wildcat (2009+), and Turf Tiger (some years). Not for 36" or 42" decks.
• OEM vs aftermarket: This is an OEM Scag part. Aftermarket alternatives (e.g., Oregon, Rotary) may differ in wheel diameter (typically 4" vs 5") and spindle design—match your original wheel’s diameter and bolt pattern (usually 3/8" or 5/16" stud).
• Measurements: Wheel diameter is 4" (some earlier models use 5"). The mounting bracket hole spacing is 2.5" center-to-center. Verify your deck’s existing bracket type (single-bolt vs two-bolt) before ordering.

Key Things to Know

• Quality: OEM build is durable polyurethane with a steel hub; less prone to cracking than some aftermarket plastic wheels.
• Installation: Easy bolt-on replacement—use a 9/16" wrench. No special tools needed, but check that the wheel spins freely after tightening.
• Common gotcha: The wheel may fit the bracket but rub the deck if your deck has a non-standard bracket offset. Measure clearance (at least 1/4") between wheel and deck underside.
• Tip: Replace anti-scalp wheels in pairs (left and right) to maintain even deck height and prevent one side from digging in.

Should You Buy It

Buy this if you own a compatible Scag zero-turn with a 48" to 72" deck and your current anti-scalp wheel is cracked, worn flat, or won’t spin. It’s a direct OEM replacement that restores proper deck float and prevents turf damage—worth the price for the fit guarantee and durability.
