Mower Anti Scalp Deck Wheel Kit for Bad Boy 022-5234-98 Kubota K5351-42110 Toro 1-603299 68-2730 Kubota K5351-42110 K5371-42110 Exmark 103-3168 Lawn-Boy Husqvarna & Many Bore 5/8" Wheel Size 4 Pack

What It Is

This 4-pack of anti-scalp deck wheels prevents the mower deck from digging into turf during turns or on uneven terrain. Designed as a direct replacement for OEM wheels on Bad Boy, Kubota, Toro, Exmark, Lawn-Boy, and Husqvarna zero-turn and lawn tractors, it keeps the deck floating at a consistent height to avoid scalping.

Fitment & Compatibility

Check your OEM part number – This kit matches Bad Boy 022-5234-98, Kubota K5351-42110 and K5371-42110, Toro 1-603299 and 68-2730, and Exmark 103-3168. It also fits many Lawn-Boy and Husqvarna models using the same bore size.

Measure the axle bore – These wheels have a 5/8" bore (0.625"). Confirm your deck’s wheel mount (stud or bolt) is 5/8" diameter. If your machine uses a 1/2" or 3/4" bore, these won’t work.

Wheel size – The 4-pack includes wheels approximately 4" diameter. Verify clearance under your deck and that the wheel diameter matches your original (too large can cause deck height issues; too small may not prevent scalping).

Deck type – Best for 42"–72" fabricated or stamped decks with anti-scalp wheel mounts. Not for walk-behind mowers or decks without wheel brackets.

Key Things to Know

• Quality vs OEM: These are aftermarket replacements. Users report they’re slightly less durable than OEM in heavy commercial use but fine for residential or light commercial mowing.
• Installation: Simple – remove the old wheel (usually a cotter pin or bolt), slide the new wheel on, and secure. No special tools needed. Expect 10–15 minutes per wheel.
• Common gotcha: Some decks use a shoulder bolt that requires a specific washer stack. If your original wheel had a spacer, reuse it. The included hardware may not match all decks.
• Lubrication: The wheels have plastic hubs. A drop of light oil on the bore before installation reduces wear and noise.

Should You Buy It

If you need a budget-friendly 4-pack to replace worn anti-scalp wheels on a compatible Bad Boy, Kubota, Toro, Exmark, or Husqvarna mower, this is a solid choice for residential or light commercial use. Skip it if you require heavy-duty commercial durability or have a non-standard bore size.
