Important: The X350 uses the newer AM144169 clutch path. Do not order the AM141536 clutch used on many earlier X300-Series tractors simply because the model name begins with X3.
The mower-deck parts depend on which deck is installed:
- 42-inch Accel Deep 42A deck: M174994 deck belt, M170639 / UC22008 standard blades, and AM144608 spindle assemblies
- Dedicated 42-inch Mulch 42M deck: M169485 primary belt, M174313 secondary belt, AM140973 or AM140332 mulching blades, and the AM137483 spindle family
- 48-inch Accel Deep 48A deck: M169485 primary belt, M169500 secondary belt, M145476 / UC22009 standard blades, and AM144608 spindle assemblies
Confirm the installed deck before ordering. The 42A, 42M, and 48A decks use different belt and blade paths.

Model Path Note
The John Deere X350 belongs to the newer Select Series generation and uses the AM144169 high-torque electric PTO clutch.
Do not assume it uses the AM141536 clutch found on many earlier X300-Series tractors.
The deck path also matters:
- 42A: one M174994 mower-deck belt
- 42M: M169485 primary belt and M174313 secondary belt
- 48A: M169485 primary belt and M169500 secondary belt
The fact that M169485 is used on both the 42M and 48A paths does not mean the complete belt systems are the same. Each deck uses a different secondary belt.
42A Accel Deep Deck Path
The X350 42A Accel Deep deck uses one M174994 mower-deck belt.
- Deck Belt: M174994
- Standard Blades: M170639 / UC22008
- Bagging Blades: GX25668
- Spindle Assemblies: AM144608
Do not confuse the 42A single-belt system with the dedicated 42M two-belt deck.
Dedicated 42M Mulch Deck Path
The dedicated 42M Mulch deck uses two separate belts:
Blade options include:
- High-Lift Mulching Blades: AM140973
- Low-Lift Mulching Blades: AM140332
The common spindle path uses the AM137483 spindle family. Match the original spindle number before ordering.
48A Accel Deep Deck Path
The X350 48A Accel Deep deck uses a two-belt drive system:
The standard blade path uses three M145476 / UC22009 mower blades.
The 48A deck uses three AM144608 spindle assemblies.
Important Fitment Check
Match the original PTO clutch number before ordering. The John Deere X350 uses the AM144169 clutch path.
Do not substitute the earlier AM141536 clutch based on the X300-Series name alone.
