ACEBRI PTO Clutch for Bad Boy: 070-1000-00, for Bad Boy 2015 2016 2017, for Bad Boy ZT Elite (2013-2016), CZT Elite (2014-2015) Clutch, for Warner: 5218-220 5218-221 350 Mower Clutch, 5100084 S SM

What It Is

The ACEBRI PTO clutch is an aftermarket electric clutch assembly that engages and disengages the mower blades on specific Bad Boy zero-turn mowers. It’s designed for commercial-grade use on ZT Elite and CZT Elite models from the mid-2010s.

Fitment & Compatibility

Before buying, verify these points:

• Direct OEM cross: Replaces Bad Boy part 070-1000-00 and Warner Electric 5218-220, 5218-221, and 350-series clutches.
• Confirmed models: Fits Bad Boy ZT Elite (2013–2016), CZT Elite (2014–2015), and 2015–2017 Bad Boy models using that clutch.
• Physical check: Measure your old clutch’s shaft diameter (typically 1-inch), bolt pattern (3-bolt, 4.25-inch spacing), and overall thickness (approx. 2.5 inches). The ACEBRI unit matches these specs, but confirm your specific deck size (48”, 54”, 60” or 72”)—the clutch itself is universal across these decks if the shaft and bolt pattern align.
• Electrical: 12V DC system with a standard 2-pin connector. Verify your wiring harness matches; if not, you may need to splice.

Key Things to Know

• Quality vs. OEM: At $125.99, it’s roughly half the price of a Bad Boy OEM clutch. User reviews indicate it holds up well for residential and light commercial use, but heavy daily commercial mowing may shorten lifespan.
• Installation difficulty: Moderate. Requires removing the deck, belt, and pulley, then unbolting the old clutch. You’ll need a puller for the old clutch if it’s seized. No special tools beyond standard wrenches and a torque wrench (tighten to 35–45 ft-lbs).
• Common gotchas: The clutch may arrive with a slightly different wire length or connector shape—plan to cut and crimp if needed. Also, the bearing can be noisy on first runs; it usually quiets after a few hours of break-in.
• Warranty: ACEBRI typically offers a 1-year warranty. Keep your receipt and test fitment immediately.

Should You Buy It

If you own a Bad Boy ZT Elite or CZT Elite from the listed years and want a budget-friendly replacement for a worn OEM clutch, this is a solid choice. It’s best for homeowners or part-time commercial operators—not for full-time, daily commercial fleets where OEM durability might be worth the extra cost.
