(Set of Two) Hustler Flat Free 13x6.50-6 Assemblies for 604898, 789537, 747782, 604717

What It Is

This is a set of two flat-free (puncture-proof) tire and wheel assemblies, sized 13x6.50-6, designed for Hustler zero-turn mowers. They replace OEM part numbers 604898, 789537, 747782, and 604717, and are ideal for commercial or residential use where flats are a recurring problem.

Fitment & Compatibility

• Primary fit: Hustler zero-turn mowers (e.g., Super Z, Fastrak, Mini Z) that use 13x6.50-6 tires with a 6-inch wheel and a 3/4-inch axle hole.
• Check your model: Verify your mower’s front tire size (stamped on sidewall) and axle diameter. Measure the wheel hub bore – it must be 3/4-inch for these assemblies.
• OEM cross-reference: These replace Hustler OEMs 604898, 789537, 747782, and 604717. If your mower uses those numbers, they’re a direct swap.
• Aftermarket note: These are aftermarket assemblies, not genuine Hustler. Quality is generally good, but verify the wheel offset matches your original (typically 1.5-inch offset on these).

Key Things to Know

• No flats, but rougher ride: Flat-free tires are solid foam – they won’t go flat, but they transmit more vibration and feel stiffer than pneumatic tires. Not ideal for bumpy turf.
• Installation is straightforward: Remove the old wheel, slide on the new one, and tighten the lug nut. No inflation or tire mounting needed.
• Weight difference: These assemblies are heavier than pneumatic tires – expect about 10-12 lbs each. This can slightly affect mower balance and turning effort.
• Longevity: Flat-free tires last multiple seasons under normal use, but they can wear faster on concrete or gravel. Check for cracking after 2-3 years.

Should You Buy It

Buy these if you mow on terrain with thorns, nails, or debris that constantly causes flats, and you want a permanent fix. They’re a good value for Hustler owners who don’t want to mess with tire repairs. Avoid if you need a cushioned ride on uneven lawns or if your axle bore is not 3/4-inch.
