What It Is

This is a flat idler pulley for the lawn mower deck, designed to guide and tension the belt on Bad Boy zero-turn mowers. It replaces OEM part numbers 033-5001-00, 033-5000-00, 280-916, and 12722.

Fitment & Compatibility

Before buying, check two things: your mower’s deck size (this fits 48", 54", and 60" decks) and your specific model. Compatible with Bad Boy CZT Elite, Outlaw XP, MZ Magnum, Renegade Stand-On, and ZT Elite series. This is an aftermarket part, not OEM Bad Boy. Measure the pulley’s outer diameter (typically 4.5 inches) and confirm the center hole is 5/8 inch. Also verify your belt width (usually 1/2 inch or 5/8 inch) to ensure the pulley groove matches. If your deck has a spring-loaded or fixed idler arm, this pulley works for both.

Key Things to Know

• Quality: Steel construction with sealed bearings. Holds up well under normal use, but not as heavy-duty as OEM for commercial mowing.
• Installation: Easy—remove the old pulley bolt, swap the pulley, and re-torque to 30-40 ft-lbs. No special tools needed.
• Common gotcha: The bearing is non-serviceable; if it fails, replace the whole pulley. Check the idler arm for wear or wobble before installing.
• Fit note: Some users report the pulley is slightly thinner than OEM, so verify belt alignment after installation to avoid rubbing.

Should You Buy It

If you need a budget-friendly replacement for a single Bad Boy zero-turn and the OEM part is out of stock or overpriced, this is a solid pick. It’s not for heavy commercial use, but for residential or light commercial mowing, it’ll do the job. Skip it if you run a mowing business and need maximum durability.
