What It Is

This is a flat idler pulley designed for Bad Boy zero-turn mowers, routing the drive belt to maintain tension and guide it around the deck spindles. It fits multiple Bad Boy series including ZT (48", 50", 54", 60"), MZ (48", 54"), and Outlaw (54", 61", 72").

Fitment & Compatibility

Before buying, confirm your mower’s deck size and model series—this pulley won’t fit non-Bad Boy brands or older/obscure models. It replaces OEM part numbers 033-8000-00, 033-2000-00, 033-7201-00, and 033-7201-25. Measure the pulley’s outside diameter (typically 4 inches) and the bearing bore diameter (usually 0.625 inches) to match your existing pulley. Check that your belt width aligns with the pulley groove (common widths: 1/2" or 5/8"). Visually compare the mounting bolt pattern and pulley thickness (often 0.625" or 0.750") to avoid clearance issues on the deck.

Key Things to Know

• Quality: This aftermarket pulley is made from stamped steel with a sealed ball bearing. It’s a direct match in dimensions to OEM, but some users report the bearing may be slightly less durable than factory Bad Boy parts under heavy use.
• Installation: Easy swap—remove the old pulley’s retaining bolt or clip, slide the new one on, and torque to spec (usually 20-30 ft-lbs). No special tools required beyond a socket wrench and belt tension release.
• Common gotchas: The pulley may fit snugly on the mounting stud—lightly sand the stud if it’s tight. Double-check belt routing after installation; misrouting can cause premature wear or misalignment.
• Price vs OEM: At $24.99, it’s roughly half the cost of a Bad Boy OEM pulley, making it a budget-friendly alternative for occasional use.

Should You Buy It

Buy this if you need a cost-effective replacement for a worn or damaged idler pulley on a Bad Boy ZT, MZ, or Outlaw mower and you’re comfortable with a basic DIY install. It’s ideal for residential users or light commercial use, but if you’re mowing professionally or want maximum bearing longevity, consider the OEM part instead.
