Stens 175-752 Pneumatic Wheel Assembly Compatible with/Replacement for Bad Boy MZ and MZ Magnum Zero-Turn mowers 022-8049-00 5/8" Bore Size, 5" Rim Size, Black

What It Is

The Stens 175-752 is a complete pneumatic wheel assembly (tire, rim, and bearing) designed as a direct replacement for the front caster wheels on Bad Boy MZ and MZ Magnum zero-turn mowers. It’s used to support the front of the mower deck and provide smooth rolling over uneven terrain.

Fitment & Compatibility

Before buying, confirm these three things:

• Bore size: 5/8” – matches the axle pin on Bad Boy MZ and MZ Magnum models. Measure your existing wheel’s bore if unsure.
• Rim size: 5” diameter – this is the rim, not the tire. The overall tire diameter is roughly 11-12” depending on inflation.
• OEM cross-reference: Replaces Bad Boy part 022-8049-00. If your mower uses that OEM number, this fits. Also fits some newer Bad Boy models with the same front caster setup.
• Not universal: This is not a generic wheel. It will not fit most residential or commercial zero-turns from other brands (e.g., John Deere, Toro, Gravely) without modifying the axle or bracket.

Key Things to Know

• Quality: Stens is a well-respected aftermarket brand. Users report the tire holds air well and the bearing is smooth out of the box. The rim is painted black steel, not plastic.
• Installation: Easy swap – remove the cotter pin and washer from the front caster, slide the old wheel off, slide the new one on, and re-pin. No special tools needed. Takes about 10 minutes per wheel.
• Common gotcha: The 5/8” bore is a tight fit on some axle pins. If your pin is rusty or has burrs, clean it up with a file or sandpaper before installing. Also, check that the tire is inflated to 20-25 PSI before use – it often ships under-inflated.
• Load capacity: Rated for the front end of a zero-turn mower (approx. 150-200 lbs per wheel). Not suitable for drive wheels or heavy-duty trailers.

Should You Buy It

If you own a Bad Boy MZ or MZ Magnum with a worn or flat front caster, this is a reliable, drop-in replacement that saves you from buying a whole OEM assembly at a higher price. It’s ideal for DIY owners who want a quick, no-fuss fix without modifying the mower. Skip it if you need a wheel for a different brand or a larger/ smaller bore size.
