8TEN Deck Wheel for Kubota RCK54-23BX RCK54-22BX RCK54-18Z RCK48-20ZG RCK54-15BX RCK54D-26BX K5351-42110 4 Pack

What It Is

This is a set of four replacement deck wheels designed to stabilize the mower deck and prevent scalping on uneven terrain. They are intended for specific Kubota zero-turn and riding mower models with 48-inch or 54-inch decks.

Fitment & Compatibility

Before buying, confirm your mower model matches one of these: Kubota RCK54-23BX, RCK54-22BX, RCK54-18Z, RCK48-20ZG, RCK54-15BX, or RCK54D-26BX. The wheels replace OEM part number K5351-42110. Measure the existing wheel’s bolt pattern (typically 3/8-inch bolt, 2-inch center-to-center) and overall diameter (around 6 inches). These are aftermarket wheels, not genuine Kubota, so verify the mounting bracket and spindle clearance on your deck—some users report needing a slight spacer for perfect alignment.

Key Things to Know

• Quality: Made from durable nylon/polyethylene, these wheels resist cracking and wear better than many OEM plastic wheels, but they are not steel or rubber.
• Installation: Easy swap—just unbolt the old wheel and bolt on the new one. No special tools required. Check that the included hardware matches your deck’s bolt size (usually M8 or 5/16-inch).
• Common gotcha: The axle hole may be slightly larger than OEM, causing wobble. If that happens, add a thin washer or use the original bolt to tighten securely.
• Durability: Rated for residential use; heavy commercial mowing may wear them faster than OEM steel wheels.

Should You Buy It

If you own one of the listed Kubota models and want a budget-friendly, direct-fit replacement that stops scalping and extends deck life, this 4-pack is a solid deal. It’s not for every Kubota deck—double-check your model number—but for the right fit, it’s a reliable, easy upgrade.
