Parts 4 Outdoor Aftermarket 4pk Deck Wheels for Xmark 103-3168 103-4051 1-603299 Made in the USA

What It Is

This is a set of four aftermarket deck wheels designed to replace worn or broken anti-scalp wheels on Xmark commercial zero-turn mowers. They help prevent the mower deck from scalping uneven terrain and protect the grass by keeping the deck at a consistent height.

Fitment & Compatibility

Before buying, confirm these exact OEM part numbers match your mower: 103-3168, 103-4051, or 1-603299. These are common on Xmark models like the Lazer Z, Turf Tracer, and Radius. Also check your deck size—these wheels fit decks from 48” to 72” typically. Measure the wheel diameter (about 6 inches) and axle hole size (5/8 inch) to be sure they’ll mount on your spindles. They are aftermarket replacements, so they may not match OEM color or finish exactly, but dimensions are identical.

Key Things to Know

• Quality: Made in the USA with durable rubber and a plastic hub. They’re solid but not heavy-duty steel—fine for residential or light commercial use.
• Installation: Easy swap—remove the old wheel, slide on the new one, and secure with the existing cotter pin or bolt. No special tools needed.
• Gotcha: The axle hole is 5/8”, but some older Xmark models may use a 1/2” axle. Measure yours before buying to avoid a loose fit.
• Durability: The rubber can wear faster on rough, rocky terrain compared to steel wheels, but they’re quieter and won’t damage the deck.

Should You Buy It

If you need a quick, affordable fix for worn deck wheels on a compatible Xmark mower and don’t want to pay OEM prices, this set is a solid choice. It’s best for homeowners or light commercial users who want reliable anti-scalp performance without the premium cost of genuine parts. Avoid if you need heavy-duty steel wheels for extreme commercial use.
