Mower Anti Scalp Deck Wheel Kit of 4 for Kubota K5371-42110 K5351-42110 Toro 1-603299 Bad Boy 022-5234-98 Exmark 103-4051 103-7263 5/8" Wheel Size

What It Is

This is a set of 4 anti-scalp deck wheels designed to prevent the mower deck from digging into the turf during turns or on uneven terrain. It fits zero-turn and riding mowers from Kubota, Toro, Bad Boy, and Exmark that use a 5/8" wheel bore.

Fitment & Compatibility

Before buying, check three things: wheel bore diameter (must be 5/8"), mounting hole spacing (verify it matches your deck’s bracket pattern), and overall wheel height (typically ~4-5" – measure your existing wheel to avoid clearance issues). This kit is an aftermarket replacement for OEM part numbers: Kubota K5371-42110 / K5351-42110, Toro 1-603299, Bad Boy 022-5234-98, and Exmark 103-4051 / 103-7263. It does not include mounting hardware or brackets – you reuse your original bolts and spacers. Always confirm your mower model year and deck size (e.g., 48", 52", 60") from your owner’s manual or parts diagram, as some decks require different wheel offsets.

Key Things to Know

• Quality vs. OEM: These are aftermarket wheels, not genuine Kubota/Toro. Expect durable plastic/nylon construction, but the bearings may be less precise than OEM – check for wobble before final tightening.
• Installation difficulty: Easy job (30-45 minutes). Requires a socket wrench and possibly a pry bar to lift the deck. No drilling or modification needed if your brackets match.
• Common gotcha: If your deck has worn or bent mounting brackets, new wheels won’t fix scalping – you may need to replace brackets first. Also, over-tightening can crack the wheel hub.
• Use case: Best for residential or light commercial use. Heavy commercial mowing may wear these faster than OEM.

Should You Buy It

If you need a budget-friendly, drop-in replacement for a worn or missing anti-scalp wheel set on a Kubota, Toro, Bad Boy, or Exmark zero-turn, this kit offers solid value at $38.69. It’s ideal for homeowners or small operators who want to restore deck stability without paying OEM premiums. Skip it if you require exact OEM fit for a commercial fleet or if your deck brackets are damaged.
