070-0055-00 Electric PTO Clutch with Wire Harness Fits for Bad Boy MZ Magnum 2017-2023 Fits for Bad Boy ZT Avenger 2020-2023 Replcace# 070-0055-00 070005500

What It Is

This is an electric PTO (power take-off) clutch with an integrated wire harness, designed to engage and disengage the mower blades on select Bad Boy zero-turn mowers. It replaces OEM part 070-0055-00 on MZ Magnum (2017–2023) and ZT Avenger (2020–2023) models.

Fitment & Compatibility

Before buying, verify your mower’s model and year—this clutch fits only the Bad Boy MZ Magnum (2017–2023) and ZT Avenger (2020–2023). Confirm your deck size (typically 48”, 54”, or 60”) doesn’t affect clutch fitment, as these decks use the same PTO assembly. Measure the existing clutch’s shaft diameter (should be 1” for these models) and bolt pattern (3-bolt, 4.25” center-to-center). If your mower has a damaged wire harness, this unit includes a replacement—just match the connector shape (2-pin flat) to your mower’s harness. Not compatible with Outlaw, Maverick, or older MZ models (pre-2017).

Key Things to Know

• Quality: Aftermarket replacement, but rated 5.0/5 from limited reviews. Expect similar lifespan to OEM (500–800 hours) if belt tension and electrical connections are correct.
• Installation Difficulty: Moderate. Requires removing the mower deck, belt, and pulley. You’ll need a 15mm socket, torque wrench (25–30 ft-lbs for mounting bolts), and possibly a puller for the old clutch.
• Common Gotchas: The wire harness plug may be tight on some Bad Boy models—test fit before reassembling. Ensure the clutch air gap is 0.010–0.020” (use a feeler gauge) for proper engagement; if not, adjust with shims.
• Check Belt Wear: Replace the drive belt if it’s cracked or glazed—a worn belt can damage the new clutch within hours.

Should You Buy It

Buy this if you own a Bad Boy MZ Magnum (2017–2023) or ZT Avenger (2020–2023) with a failed PTO clutch and want a direct-fit replacement at a lower cost than OEM. It’s a solid choice for DIY repairs, but skip it if you need a clutch for older models or non-Bad Boy brands—fitment is strict.
