Scag Anti-Scalp Roller Replaces Scag 481632 Fits Most scag Units Including Turf Tiger Includes Bushing.

What It Is

The Scag Anti-Scalp Roller (replacement for OEM part 481632) is a deck-mounted wheel that prevents the mower deck from digging into turf during turns or on uneven ground. It’s designed for most Scag zero-turn and walk-behind mowers, including the Turf Tiger, and comes with a bushing pre-installed for smooth rotation.

Fitment & Compatibility

Before buying, check:

• Deck size and model: Fits Scag 48”, 52”, 61”, and 72” decks on Turf Tiger, Cheetah, Wildcat, Tiger Cat, and Patriot models. Not compatible with 36” or 42” decks.
• OEM vs aftermarket: This is a genuine Scag part, not a generic aftermarket. It directly replaces part number 481632. If your mower uses a different roller (e.g., 481631 or 481633), it will not fit.
• Measurements: The roller is 4” diameter with a 0.625” (5/8”) inner bore. Verify your existing roller’s diameter and shaft size before ordering.
• Bushing included: Yes, but confirm your deck’s mounting bracket accepts this bushing style—some older decks may need a separate spacer.

Key Things to Know

• Quality: Genuine Scag steel roller with sealed bearing—holds up better than plastic aftermarket versions on rocky or hard-packed soil.
• Installation: Easy bolt-on job. Remove the old roller’s retaining clip and bolt, slide off the old unit, then mount the new one. No special tools required.
• Common gotcha: The included bushing may be slightly tight on some shafts. Lightly sand the shaft if it doesn’t slide on freely—don’t force it.
• Maintenance: Check for play after 50 hours of use. Worn bushings cause scalping—replace both rollers on the same axle at the same time for even wear.

Should You Buy It

Buy it if you own a Scag zero-turn with a deck 48” or larger and need a direct OEM replacement for a worn or damaged anti-scalp roller. It’s a fair price for genuine Scag quality, and the included bushing saves a separate purchase. Skip if your mower uses a different roller size or if you prefer a cheaper aftermarket plastic option—but expect shorter lifespan.
