Bad Boy 070-0056-00 and 070-1000-00 are different PTO clutch replacements. Both use a 1-1/8-inch bore and CCW rotation in the replacement configurations compared here, but the pulley sizes differ: 5.94 inches for 070-0056-00 versus approximately 6.3 inches for 070-1000-00.

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
Shared bore size and rotation can make two clutch listings look similar at a glance. The original clutch number, pulley dimensions, wiring and mounting arrangement distinguish the 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.
A different drive-pulley diameter changes the deck-drive ratio. The replacement also needs the correct pulley position, belt groove and mounting geometry for your mower.
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
- 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 formats: 70-1000-00, 070100000
- Warner cross-reference: 5218-220, 5218-114
- Other cross-references: Stens 255-775, Xtreme X0244
- Bobcat / Bunton / Ryan path: 4164976
- Pulley diameter: approximately 6.3 inches (6.31-inch catalog reference)
- 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.
070-1000-00: Standard or HD Upgrade?
Standard: Black pulley, flat side-by-side connection at the clutch body, and a removable extension harness for a T-style mower plug.
HD Upgrade: Silver pulley, larger bearing design and a hardwired lead ending in a T-style plug. This version has no flat side-by-side socket at the clutch body.
Match your mower-side connector when choosing the option. Both are sold for the 070-1000-00 replacement application; the HD option is not a conversion for 070-0056-00.
Compare Standard & HD OptionsThe 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
The clutch pulley drives the deck belt. Changing its diameter changes the drive ratio, while the belt, idlers and tensioner must still operate within their designed range. A shared bore size does not settle those requirements.
Match both pulley diameter and pulley offset. Diameter affects drive ratio and the belt length taken up around the pulley; offset affects alignment with the rest of the belt drive. Use the specified replacement instead of choosing whichever clutch fits the crankshaft.
Common Bad Boy Model Split
These model families help narrow the lookup. Confirm the part number in the manual for your mower’s year and configuration; the model name alone is not a fitment confirmation.
On smaller screens, scroll across the table to compare all columns.
| Model / Series | Clutch Reference to Check | 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?
Check Ogura versus Warner before choosing a replacement. Bad Boy’s official 070-0056-00 listing specifically calls for that check on 2025 mowers and identifies 070-0059-00 for Warner-equipped machines.
For later years, use that year’s manual and the installed clutch label. Send both tags to our Parts Desk if the numbers differ.
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?

Does 070-0056-00 replace 070-1000-00?
No. Do not treat 070-0056-00 as a direct replacement for 070-1000-00. Their pulley sizes and application requirements differ. Match your original clutch number and physical configuration.

Our 070-1000-00 replacement uses an approximately 6.3-inch pulley, also described as 6.31 inches in catalog references.
Why does pulley size matter on a PTO clutch?
Drive-pulley diameter affects the deck-drive ratio and the belt length taken up around the pulley. Pulley offset affects belt alignment. Both dimensions need to suit the mower’s belt drive.
Can PTO Direct USA help identify my Bad Boy PTO clutch?
