Important: The X390 uses the AM144169 clutch path. Do not order the earlier AM141536 clutch used on many older X300-Series tractors based on the X3 model family alone.
The mower-deck parts depend on which Accel Deep deck is installed:

- 54-inch Accel Deep 54A deck: M169485 primary belt, M169486 secondary belt, and UC22010 standard blades

Model Path Note
The John Deere X390 uses the AM144169 high-torque electric PTO clutch.
The main deck-parts split is between the 48A and 54A Accel Deep decks.
- 48A: M169485 primary belt, M169500 secondary belt, and UC22009 standard blades
- 54A: M169485 primary belt, M169486 secondary belt, and UC22010 standard blades
Both decks use M169485 as the primary belt, but they use different secondary belts.
Do not copy the X380 48A belt path onto the X390. The X380 48A guide lists M169500 as a single mower-deck belt, while the X390 48A guide lists M169485 as the primary belt and M169500 as the secondary belt.

The official replacement-parts guide also lists M127673 as the mulch blade reference for the 48A deck.
