What It Is

This is a set of four flat idler pulleys designed to guide and tension the drive belt on Bad Boy zero-turn mowers. They replace worn pulleys that cause belt slipping, noise, or poor blade engagement, and fit select ZT, MZ, and Outlaw models with 48" to 72" decks.

Fitment & Compatibility

Before buying, confirm your mower’s deck size and model series. These pulleys fit:

• Bad Boy ZT models: 48", 50", 54", 60" decks
• Bad Boy MZ models: 48", 54" decks
• Bad Boy Outlaw models: 54", 61", 72" decks

They replace OEM part numbers 033-8000-00, 033-2000-00, 033-7201-00, and 033-7201-25. Measure your existing pulley: outer diameter should be approximately 4.0" (check your belt routing diagram for exact spec). Verify the bearing bore size (typically 5/8" or 3/4") and the pulley flange width matches your belt. These are aftermarket, not OEM Bad Boy parts, so test fitment on one pulley before installing all four.

Key Things to Know

• Quality: Made from stamped steel with sealed ball bearings. Expect decent durability for residential use; commercial operators may wear them faster than OEM.
• Installation: Easy—remove belt, unbolt old pulley, bolt on new one. Use a socket wrench; torque to 20-25 ft-lb. No special tools.
• Gotcha: The set includes four pulleys, but your deck may use only two or three idlers. Check your parts diagram to avoid buying extras you don’t need.
• Belt compatibility: These pulleys work with standard 1/2" or 5/8" belts. If your belt is wider or narrower, measure carefully or consult your manual.

Should You Buy It

Buy this set if you need to replace multiple worn idler pulleys on a Bad Boy ZT, MZ, or Outlaw mower and want a cost-effective aftermarket option. It’s a solid choice for residential users who can confirm fitment via measurements and OEM numbers. For commercial use, consider OEM for longer lifespan.
