Exmark 130-0736 Caster Wheel Quest E S Series

What It Is

The Exmark 130-0736 is an OEM replacement caster wheel assembly designed for the front axle of Exmark Quest and E-Series zero-turn mowers. It provides the steering and support needed for maneuverability on residential and commercial turf.

Fitment & Compatibility

• Exact fit for: Exmark Quest (all sub-models) and E-Series (E, ES, EZ) zero-turn mowers built from 2008 onward.
• Check before buying: Measure the existing wheel diameter (typically 11 x 4.00-5) and verify the spindle/pin diameter (usually 5/8"). The 130-0736 includes the wheel, tire, bearing, and axle bolt—no separate hub needed.
• OEM only: This is an Exmark genuine part. Aftermarket alternatives (e.g., from Stens or Oregon) exist but may use different bearing specs or softer tires, affecting ride and durability.
• Not for other brands: Will not fit Toro, John Deere, or Scag zero-turns without significant modification.

Key Things to Know

• Quality: OEM construction is robust, with a heavy-duty tire and sealed bearings. However, a 3.0 rating suggests some users report premature bearing wear or flat spots from storage.
• Installation difficulty: Easy (15–30 min). Remove the old caster by pulling the cotter pin and washer, slide on the new assembly, and secure with the provided pin. No special tools required.
• Common gotchas: The tire is air-filled (not foam-filled), so check pressure regularly (15–20 psi). Overinflation or underinflation can cause wobble or rapid tread wear. Also, verify the axle bolt length matches your deck—some Quest models use a longer bolt.
• Cost vs. value: At $82, it’s pricier than aftermarket (often $50–60), but the OEM fit is guaranteed. If you’re on a tight budget, aftermarket is viable if you confirm bearing and tire specs.

Should You Buy It

Buy the Exmark 130-0736 if you want a no-hassle, drop-in replacement that matches your mower’s original steering feel and durability. It’s ideal for owners who prioritize OEM reliability over saving $20–30. Skip it if you’re comfortable measuring and sourcing an aftermarket wheel, or if your current caster only needs a tire replacement (sold separately for ~$20).
