Lawn Mower Anti Scalp Deck Wheel Kit Set of 4 Compatible with Hustler 788166 31997 Rotary 13445 MTD John Deere & More Models

What It Is

This is a set of four anti-scalp deck wheels designed to prevent the mower deck from digging into turf on uneven ground. They fit a wide range of zero-turn and riding mowers from Hustler, John Deere, MTD, Rotary, and others, and are a direct replacement for OEM part numbers 788166, 31997, and 13445.

Fitment & Compatibility

Before buying, confirm three things:

• Deck thickness: The included mounting brackets fit decks with a 1/4″ to 3/8″ wall thickness. Measure your deck lip.
• Bolt pattern: The wheels use a 5/16″ bolt. Check that your existing holes are the same size or that you can drill new ones.
• Model cross-reference: This kit is listed for Hustler (788166, 31997), Rotary (13445), MTD, and John Deere decks. However, not all John Deere decks use the same bracket geometry—verify that the bracket’s offset matches your deck’s front edge clearance.
• Wheel diameter: Each wheel is approximately 4″ tall. Ensure this won’t raise your deck too high for your desired cut height (typical range: 1.5″–4″).

Key Things to Know

• Installation difficulty: Moderate. Requires basic hand tools and possibly a drill if your deck lacks pre-drilled holes. Expect 30–60 minutes.
• Quality notes: Wheels are hard plastic with steel bushings—adequate for residential use but may wear faster on gravel or concrete. Brackets are painted steel; check for rust protection if you store outdoors.
• Common gotcha: The brackets are universal, not deck-specific. You may need to bend or shim them for proper wheel alignment. Test roll height before tightening fully.
• Set of four: Two wheels go on the front corners, two on the rear. Some decks only need two—check your manual.

Should You Buy It

Buy this kit if you have a Hustler, Rotary, or MTD zero-turn with a flat deck lip and want an affordable anti-scalp solution. It’s a solid value for residential use, but if you mow commercial terrain with frequent bumps, consider OEM or heavier-duty wheels with ball bearings for longer life.
