Spartan (OEM) 422-0001/422-0061-00-00 Anti Scalp Wheel for Spartan Zero Turn Mowers

What It Is

This is the OEM anti-scalp wheel assembly for Spartan zero-turn mowers (part #422-0001 / 422-0061-00-00). It prevents the mower deck from digging into turf on uneven terrain, protecting both your grass and the deck.

Fitment & Compatibility

• Fits: Spartan zero-turn mowers with stamped or fabricated decks that use a 3/8" shoulder bolt and a wheel with a 1/2" inner diameter bearing. Common on 48", 52", 54", 60", and 72" decks.
• Check before buying: Remove your old wheel and measure the bolt hole diameter (must be 1/2") and the wheel width (typically 2" on Spartan OEM). Verify you have the correct shoulder bolt length (usually 1.5"–2").
• OEM vs aftermarket: This is genuine Spartan – exact fit, no tweaking. Aftermarket wheels may use different bearings or smaller rubber tires, causing wobble or premature wear.
• Models: Confirmed for Spartan SRT, RT, RZ, and Pro series. If your mower has a different wheel mount (e.g., vertical pin vs horizontal bolt), this won’t work.

Key Things to Know

• Quality: The wheel is a hard plastic with a sealed bearing – durable but not puncture-proof. It won’t flat-spot like rubber wheels.
• Installation: Easy – remove the old bolt and wheel, slide the new one on, and torque the bolt to 20-25 ft-lbs. Use a thread locker if the bolt keeps loosening.
• Common gotcha: The bearing is pre-lubricated, but if you pressure-wash the deck, water can get in and seize it. Let it dry after washing.
• Price note: $30.78 is typical for OEM; aftermarket versions cost $10-15 but often fail within a season.

Should You Buy It

If you own a Spartan zero-turn and your current anti-scalp wheel is cracked, worn, or missing, this is the right fix. It’s a direct OEM replacement that will last 2-3 seasons under normal use. Skip aftermarket options unless you’re on a tight budget and okay with replacing them yearly.
