Quick Answer
The John Deere Z245 has more than one PTO clutch and mower-deck belt path, so the serial number and original clutch number matter.
- Z245 through serial 100000: AM136115 PTO clutch path
- Other Z245 applications: AM138729 clutch path — confirm the original clutch number before ordering

Model Path Note
The John Deere Z245 should not be treated as a single clutch-and-belt configuration.
For the PTO clutch:
- AM136115: confirmed Z245 path through serial 100000
- AM138729: separate Z245 clutch path used on other production applications
For the 48-inch mower-deck belt:
- Serial 100000 and below: M154621
- Serial 100001 and above: M158130
Match the original PTO clutch number before ordering. Do not assume the clutch and deck belt are the same across every Z245 production range.
Early Z245 Path — Serial 100000 and Below
For Z245 mowers through serial 100000, the confirmed PTO clutch path uses AM136115.
- PTO Clutch: AM136115
- 48-Inch Deck Belt: M154621
- Standard Blades: GY20852 / GX21784
- Spindle Assembly: AM136733 / AM137483
Later Z245 Deck Path — Serial 100001 and Above
For Z245 mowers beginning at serial 100001, the confirmed 48-inch mower-deck belt changes to M158130.
- 48-Inch Deck Belt: M158130
- Standard Blades: GY20852 / GX21784
- Spindle Assembly: AM136733 / AM137483
Later Z245 applications can use the separate AM138729 PTO clutch path. Match the original clutch number or official model-specific parts diagram before ordering the clutch.
Important Fitment Check
Match the original PTO clutch number before ordering. The John Deere Z245 can use the AM136115 or AM138729 clutch path depending on the production setup.
Do not substitute one clutch for the other based on the Z245 model name or 48-inch deck size alone.
