Looking for a Grasshopper 225, 225V or 225V-G4 PTO clutch? Start with the complete model and serial number. The factory catalogs below identify three clutch references: 388740, 388751 and 388750.
Use the model table to find the correct OEM reference, then compare the replacement's specifications and mounting details. Deck belts, blades and idlers require a separate match to the installed deck.
Which PTO Clutch Fits the Grasshopper 225 Family?
These are specific catalog examples. Match your mower's full model, production year and serial number in the Grasshopper parts lookup before selecting a replacement.
| Mower model | Catalogs checked | OEM clutch | Next step |
|---|---|---|---|
| 225 | 2004 and 2020 | 388740 | Compare the 388740 replacement's specifications and photos below. |
| 225V | 2017 | 388751 | Send your clutch label and model/serial tag for help. |
| 225V-G4 | 2024 | 388750 | Compare the 388750 replacement's specifications and photos below. |
Open Drive Assembly in the 225 and 225V catalogs, or Drive & Steering Assembly for the 2024 225V-G4. The links may first open the model's assembly menu.
The 2004 and 2020 entries are two checked catalogs, rather than a verified year-by-year range. For other production years, use the matching catalog. Grasshopper's official manual lookup accepts the mower serial number.

Check the Mounting Arrangement Before Ordering
- Identify the mower. Record the full model, including V or V-G4, and serial number.
- Identify the clutch. Photograph its Grasshopper, Warner or other manufacturer label and confirm the OEM reference in the matching diagram.
- Compare the complete fit. Check the bore and key, pulley dimensions and offset, belt position, specified rotation, electrical connector, anti-rotation stop and mounting clearances.
Follow the mower and clutch manufacturer's instructions for the mounting hardware, torque and any required break-in procedure. Our clutch installation guide provides a general overview.
