Parts 4 Outdoor 2Pk Aftermarket Single Wheel Kit for Ariens Gravely 03905900 00473600 06200321 00473800

What It Is

This is a 2-pack of aftermarket single wheels designed to replace the front caster or anti-scalp wheels on zero-turn mowers, specifically Ariens and Gravely models. It helps prevent scalping on uneven terrain by keeping the mower deck level.

Fitment & Compatibility

• OEM Replacements: Fits Ariens/Gravely part numbers 03905900, 00473600, 06200321, and 00473800.
• Check Your Mower: Works on most Ariens Ikon, Zoom, and Gravely ZT series with 42-60” decks. Verify your deck’s wheel mount uses a 5/8” axle hole (common on these models).
• Measurements: Each wheel is roughly 4” diameter x 1.5” wide with a solid rubber tire. Measure your old wheel’s diameter and axle hole before ordering.
• Aftermarket Note: Not OEM; may have slight differences in tread pattern or rubber hardness. Check if your deck uses a spindle or bracket—these are direct bolt-on replacements for the listed OEM parts.

Key Things to Know

• Quality: Solid rubber tires (not pneumatic) so no flats, but they can be harder than OEM, leading to a slightly rougher ride on bumpy lawns.
• Installation: Easy—remove bolt, swap wheel, tighten. No special tools needed. Use a thread-locker if your deck vibrates heavily.
• Common Gotcha: The axle bolt may be metric or SAE depending on your mower’s year; have a 1/2” or 13mm socket ready. If your old wheel has a bearing, this one uses a plain bushing—add a drop of oil if it squeaks.
• Durability: Rated for residential use; heavy commercial mowing may wear the rubber faster than OEM.

Should You Buy It

Buy this if you need a budget-friendly, direct replacement for worn front wheels on your Ariens or Gravely zero-turn and don’t mind slightly harder rubber. Skip it if you require exact OEM feel or run a commercial mower 40+ hours a week.
