If you are comparing a Bad Boy 070-0056-00 PTO clutch with a Bad Boy 070-1000-00 PTO clutch, stop before ordering. These two clutch families are commonly confused in aftermarket catalogs, but they are not the same clutch path.
The confusion usually comes from one shared spec: both clutch families may use a 1-1/8 inch crankshaft bore and CCW rotation. That does not make them interchangeable. The major difference is pulley size. The 070-0056-00 clutch uses a smaller 5.94-inch pulley, while the 070-1000-00 clutch uses a larger 6.31-inch pulley.
That pulley difference matters. Installing the wrong PTO clutch can cause belt slip, heat buildup, weak blade speed, poor cut quality, premature belt wear, and early clutch failure.

| Bad Boy PTO Clutch | Pulley Diameter | Bore Size | Rotation | Common Model Path | Replacement Path |
|---|---|---|---|---|---|
| 070-0056-00 | 5.94 inches | 1-1/8 inch | CCW | ZT Elite, Maverick, Revolt SD, Raider, Walk-Behind | 070-0056-00 PTO Clutch |
| 070-1000-00 | 6.31 inches | 1-1/8 inch | CCW | Pup, Lightning, Outlaw, Outlaw Extreme, Outlaw XP, CZT, legacy ZT | 070-1000-00 PTO Clutch |
Important fitment warning: Do not choose by bore size alone. A 1-1/8 inch bore match does not confirm PTO clutch fitment. Pulley diameter, connector style, anti-rotation setup, deck belt geometry, and the original clutch number still matter.
Why These Two Bad Boy PTO Clutches Get Confused
Many aftermarket listings group PTO clutches together when they share one or two specs, such as bore size or rotation. That is risky with Bad Boy PTO clutches because several different clutch families can share a 1-1/8 inch bore while using different pulley diameters, torque ratings, wiring layouts, and mower applications.
The 070-0056-00 and 070-1000-00 clutch families are a perfect example. They both use a 1-1/8 inch bore and CCW rotation, but the pulley sizes are different enough that they should not be treated as the same replacement path.
If your mower was built around a 6.31-inch pulley and you install a 5.94-inch pulley clutch, the belt system may not maintain proper tension or blade speed. If your mower was built around a 5.94-inch pulley and you install a 6.31-inch pulley clutch, belt alignment, belt tension, and deck-drive speed can also be wrong.
Bad Boy 070-0056-00 PTO Clutch Path
The Bad Boy 070-0056-00 PTO Clutch is the smaller-pulley clutch path. It is commonly associated with newer Bad Boy mower platforms such as ZT Elite, Maverick, Revolt SD, Raider, and Walk-Behind applications when the original clutch number and specs match.
- Primary part number: 070-0056-00
- Common number format: 070005600
- Related Bad Boy number: 056-8058-00
- Pulley diameter: 5.94 inches
- Crankshaft bore: 1-1/8 inch
- Rotation: CCW from pulley side
- Common applications: select ZT Elite, Maverick, Revolt SD, Raider, and Walk-Behind mower applications
070-0056-00 fitment note: Do not list or treat 070-1000-00 as a clean direct replacement for this clutch. The 070-1000-00 path uses a larger 6.31-inch pulley and belongs to a different clutch family.
Bad Boy 070-1000-00 PTO Clutch Path
The Bad Boy 070-1000-00 PTO Clutch is the larger-pulley heavy-duty clutch path. It is commonly associated with older and heavier Bad Boy commercial mower families such as Pup, Lightning, Outlaw, Outlaw Extreme, Outlaw XP, CZT, and legacy ZT applications when the original clutch number and specs match.
- Primary part number: 070-1000-00
- Common number format: 70-1000-00
- Warner cross-reference: 5218-220, 5218-114
- Other cross-references: Stens 255-775, Xtreme X0244
- Bobcat / Bunton / Ryan path: 4164976
- Pulley diameter: 6.31 inches
- Crankshaft bore: 1-1/8 inch
- Rotation: CCW from pulley side
- Common applications: select Pup, Lightning, Outlaw, CZT, and legacy ZT mower applications
070-1000-00 fitment note: Do not order this clutch for newer Bad Boy ZT Elite, Maverick, Revolt SD, Raider, or Walk-Behind applications unless your original clutch number and pulley diameter confirm the 070-1000-00 path.
The Pulley Size Trap
The most important difference between these two clutch paths is the pulley diameter:
- 070-0056-00: 5.94-inch pulley
- 070-1000-00: 6.31-inch pulley
That difference may not sound huge, but on a mower deck drive system it can change belt tension, belt tracking, and blade speed. A mower deck is designed around a specific pulley size. The belt, idlers, tensioner spring, spindle pulleys, and deck geometry all work together.
If the replacement clutch pulley is too small, the belt can run loose, slip under load, overheat, and fail early. If the replacement pulley is too large, the belt can be over-tensioned, misaligned, or driven at the wrong speed. Either mistake can damage the clutch, belt, idlers, or deck-drive system.
Common Bad Boy Model Split
| Model / Series | More Likely Clutch Path | Fitment Note |
|---|---|---|
| ZT Elite | 070-0056-00 | Common on many modern ZT Elite applications. Confirm original clutch number. |
| Maverick | 070-0056-00 | Common on many modern Maverick applications. Confirm year and clutch label. |
| Revolt SD | 070-0056-00 | Common on newer Revolt SD applications. Confirm original clutch and pulley. |
| Raider | 070-0056-00 | Common on newer Raider applications. Confirm by parts diagram. |
| Walk-Behind | 070-0056-00 | Common on newer walk-behind applications. Confirm original clutch number. |
| Pup | 070-1000-00 | Common on legacy Pup applications using the larger pulley path. |
| Lightning | 070-1000-00 | Common on Lightning 5200, 6000, and 7200 style applications. |
| Outlaw / Outlaw Extreme / Outlaw XP | 070-1000-00 | Common on heavier legacy commercial applications. |
| CZT / CZT Elite | 070-1000-00 | Common on selected commercial CZT applications. Do not confuse CZT Elite with ZT Elite. |
| Legacy ZT | 070-1000-00 | Older ZT applications may use the larger 070-1000-00 clutch path. |
Model-name warning: Bad Boy model names can overlap across generations. Do not order by model name alone. Always match the original clutch number and pulley diameter before installing a replacement PTO clutch.
Do Not Confuse CZT Elite With ZT Elite
One common source of confusion is the word Elite. A CZT Elite application may route differently than a modern ZT Elite application. The CZT path is commonly tied to the larger 070-1000-00 clutch family, while many modern ZT Elite applications are tied to the smaller 070-0056-00 clutch family.
If your mower name includes “Elite,” do not stop there. Check the full model, year, deck size, and original clutch part number.
What About Warner 5218-220?
Warner 5218-220 is tied to the 070-1000-00 clutch path, not the 070-0056-00 path. If your original clutch label shows Warner 5218-220 or Warner 5218-114, compare the replacement against the 070-1000-00 PTO Clutch.
Some catalogs may mention nearby Warner numbers, but the safest method is to confirm the original clutch number, pulley diameter, bore size, connector style, and rotation before ordering.
What About 2025 and Newer Bad Boy Mowers?
Some newer Bad Boy ZT Elite and Maverick models may use a newer Warner-style clutch path instead of the earlier 070-0056-00 Ogura-style path. If your mower is a 2025 or newer model, check the clutch installed on the mower before ordering.
If your mower calls for 070-0059-00 or requires a Bad Boy conversion kit, do not assume that 070-0056-00 is a direct plug-and-play replacement. Match the brand, part number, pulley diameter, connector, and mounting setup on your original clutch.
Before Ordering Either Bad Boy PTO Clutch
Before ordering a replacement PTO clutch for your Bad Boy mower, confirm:
- Original clutch number: match the number stamped, printed, labeled, or shown in the parts manual
- Pulley diameter: 5.94 inches for 070-0056-00, or 6.31 inches for 070-1000-00
- Crankshaft bore: confirm 1-1/8 inch
- Rotation: confirm CCW from pulley side
- Connector style: compare plug style, wire length, and routing
- Anti-rotation setup: confirm bracket or stop position
- Deck belt path: check belt routing, idlers, spindles, and pulley alignment
- Mower model and year: verify using the mower model tag and parts diagram
Review the PTO clutch installation guide before installing the replacement. If the old clutch will not slide off the crankshaft, use the PTO clutch stuck on crankshaft guide before forcing removal.

FAQ
Are Bad Boy 070-0056-00 and 070-1000-00 the same PTO clutch?
No. They are separate clutch families. Both may use a 1-1/8 inch bore and CCW rotation, but the pulley sizes are different. The 070-0056-00 clutch uses a 5.94-inch pulley, while the 070-1000-00 clutch uses a larger 6.31-inch pulley.
Does 070-0056-00 replace 070-1000-00?
No. Do not treat 070-0056-00 as a direct replacement for 070-1000-00. The pulley diameter difference can cause belt slip, heat buildup, poor blade speed, and premature clutch failure.
