(Set of 2) Gravely/Ariens Pneumatic 11x4.00-5 Light Gray Assys replaces 07100124 Fits ZT, XL, X, Zoom, Zoom XL

What It Is

This is a set of two pneumatic (air-filled) front caster wheel assemblies, 11x4.00-5, designed for Gravely and Ariens zero-turn mowers (ZT, XL, X, Zoom, Zoom XL series). They replace OEM part 07100124 and are used for smooth rolling over turf and uneven ground.

Fitment & Compatibility

• Check your model series: Fits Gravely ZT, XL, X, and Zoom XL models. Also fits Ariens Zoom and Zoom XL. Not for all Gravely/Ariens models—double-check your deck size and year.
• Measure your existing wheel: The tire size is 11x4.00-5 (11" diameter, 4" wide, 5" rim). Verify your old wheel matches these dimensions.
• OEM vs aftermarket: These are aftermarket replacements for OEM part 07100124. They are not genuine Gravely/Ariens, so check that your axle and hub bore (typically 5/8" or 3/4") are compatible.
• Assembly includes: Two complete wheel assemblies (tire, tube, rim, bearings, and hardware). No need to buy extra parts unless your axle is a different size.

Key Things to Know

• Pneumatic vs solid: These are air-filled, so they provide a smoother ride but can go flat. Check tire pressure before first use (usually 15-20 PSI).
• Installation difficulty: Easy—usually a single bolt/nut on the caster fork. You may need a wrench and jack to lift the mower.
• Common gotchas: The light gray color may show dirt/stains faster than black. Ensure your caster fork is in good shape (no bent or worn bushings) or the new wheels won’t track straight.
• Quality note: With 4.4 stars from 72 reviews, these are generally well-regarded but some users report slightly softer rubber than OEM. Fine for residential use; heavy commercial use may wear faster.

Should You Buy It

If you need a direct, affordable replacement for worn or flat front wheels on a Gravely or Ariens ZT/XL/Zoom mower, and you’re confident in the fitment (check axle size and model series), this set is a solid value. It’s not for heavy-duty commercial fleets, but for homeowners or light commercial use, it beats paying double for OEM.
