033-8000-00 Flat Idler Pulley, Lawn Mower Idler Pulley Compatible with Bad Boy 48" 50" 54" 60" ZT Series, 48" 54" MZ Series, 54" 61" 72" Outlaw Series Replaces# 033-2000-00, 033-7201-00, 033-7201-25

What It Is

The 033-8000-00 is a flat idler pulley that guides and tensions the mower deck belt on Bad Boy zero-turn mowers. It is a direct replacement for worn or seized pulleys on 48", 50", 54", and 60" ZT series, 48" and 54" MZ series, and 54", 61", and 72" Outlaw series mowers.

Fitment & Compatibility

Before purchasing, verify your mower’s deck size and model series against the listed Bad Boy models (ZT, MZ, Outlaw). This pulley replaces OEM part numbers 033-2000-00, 033-7201-00, and 033-7201-25. Measure the pulley’s outer diameter (typically 4.0") and bore size (usually 5/8") to confirm it matches your existing pulley. Check that the pulley is flat (not grooved) and that the belt rides on the flat face—if your deck uses a grooved idler, this will not work.

Key Things to Know

• Quality: Made from steel with a sealed bearing; rated 4.6/5 stars. Most users report it runs quietly and lasts as long as OEM.
• Installation: Moderate difficulty—requires removing the deck belt and a single bolt. A socket wrench and possibly a puller for seized pulleys are needed.
• Common gotcha: The pulley may not include the mounting bolt or spacer—reuse your original hardware. If the bearing feels rough or gritty out of the box, return it.
• Fitment nuance: While listed for multiple Bad Boy decks, some users with older Outlaw models needed to add a washer to align the belt properly.

Should You Buy It

Buy this pulley if you need an affordable, direct replacement for a worn Bad Boy idler pulley on a ZT, MZ, or Outlaw series mower and you are comfortable with basic deck maintenance. It is a solid aftermarket choice if you want to save money over OEM without sacrificing reliability. Skip it if your deck uses a grooved or non-standard size pulley.
