What It Is

This is a replacement anti-scalp deck wheel for zero-turn and riding mowers. It prevents the mower deck from digging into turf on uneven ground, reducing scalping damage. Designed for Kubota, Exmark, and Toro commercial and residential models.

Fitment & Compatibility

• Cross-references: Replaces OEM part numbers 103-3168, 68-2730, K5371-42110, 1-603299, 103-7263, 103-4051.
• Measure before buying: Wheel outer diameter is 4 inches, axle hole is 5/8 inch, and overall height is 4.5 inches. Confirm your deck’s mounting bracket and spindle clearance.
• Brand fit: Fits many Kubota Z-series, Exmark Lazer Z and Quest, and Toro TimeCutter and Titan models. Not universal—verify your deck’s wheel bracket type (flat or offset).
• Aftermarket note: This is a non-OEM replacement. Quality is comparable to OEM, but tolerances may vary slightly. Check for any burrs on the axle or wheel bore before installation.

Key Things to Know

• Build quality: Hard plastic wheel with a steel bearing sleeve. Durable enough for residential use; commercial operators may prefer OEM for longer life under heavy daily use.
• Installation: Easy—remove the old wheel’s retaining clip or bolt, slide the new wheel on, and secure. No special tools needed. Takes 5-10 minutes per wheel.
• Common gotcha: The axle hole is 5/8 inch, but some older decks use 1/2-inch axles. Measure your existing wheel’s bore before ordering. Also, check that the wheel spins freely after installation—binding can cause premature wear.
• Set of four? Sold individually. If replacing all deck wheels, buy four to maintain even deck height.

Should You Buy It

Buy this if you need a budget-friendly, direct-fit replacement for a worn or damaged anti-scalp wheel on a Kubota, Exmark, or Toro mower with a 5/8-inch axle. It’s a solid value for residential users and light commercial use, but heavy-duty commercial operators should stick with OEM for maximum durability.
