2 Pack 033-7201-25 Idler Pulley Replaces 033-7201-00 033-2000-00 033-8000-00 15422 for Bad Boy MZ Magnum 54" 48", ZT Elite 60" 54" 48", Maverick 60" 54", Outlaw 54" 61" 72" Decks

What It Is

This is a 2-pack of idler pulleys (OEM cross-reference 033-7201-25) that guide and tension the drive belt on Bad Boy zero-turn mowers with 48", 54", 60", 61", or 72" cutting decks. Replaces worn or noisy pulleys to prevent belt slippage and deck vibration.

Fitment & Compatibility

Before buying, confirm:

• Deck size & model: Fits Bad Boy MZ Magnum (48", 54"), ZT Elite (48", 54", 60"), Maverick (54", 60"), Outlaw (54", 61", 72"). Does not fit all Bad Boy models—check your deck’s specific year and model number.
• OEM cross-references: Replaces 033-7201-00, 033-2000-00, 033-8000-00, and 15422. If your pulley has any of these numbers stamped on it, this will work.
• Measurements: Pulley diameter is approximately 3.5" (verify against your old pulley). Shaft bore is 5/8" with a 1/4" set screw. Measure your spindle shaft diameter and bolt pattern before ordering.
• Bearing type: Sealed ball bearing (no grease fitting). If your deck uses a greasable pulley, this is a different part.

Key Things to Know

• Quality: All-metal construction with a sealed bearing. Users report it lasts 2–3 seasons on residential use, but commercial mowing may require more frequent replacement.
• Installation difficulty: Moderate. You’ll need a socket set, a 3/16" Allen wrench (for the set screw), and possibly a puller if the old pulley is seized. Plan 20–40 minutes per pulley.
• Common gotcha: The set screw is small and can strip easily—use a quality Allen key and don’t overtighten. Also, verify the belt routing after installation; a misaligned pulley can cause belt chirping.
• Pack value: Two pulleys for $37.99 is roughly half the cost of buying two OEM singles. If you need just one, you’ll have a spare.

Should You Buy It

Buy this 2-pack if you own one of the listed Bad Boy ZT models and need to replace a noisy or wobbly idler pulley. It’s a solid aftermarket alternative at a fair price for the pair, with good user feedback on durability. Avoid if your deck uses a different bore size (e.g., 3/4") or a greasable pulley design.
