Part of the John Deere Repair Manuals.
This 752-page John Deere X330 Technical Manual (OEM #TM138119) covers the full Select Series lawn tractor lineup: X330, X350, X354, X370, X380, X384, X390, and X394. You get wiring diagrams for every model's harness, hydraulic schematics for the lift and drive systems, plus a dedicated DTC section that turns a blinking dash light into an actual answer instead of a guessing game. Set the blower housing screws to 9 N·m (80 lb-in) and torque the muffler flange nut on the 44J677 engine to 22 N·m, straight from the factory table, not a forum thread. Your key switch fuse pulls 15A; know that before you start swapping parts that aren't the problem. One tractor down for a wiring gremlin costs more than this manual ever will. Bookmarked by section and searchable by keyword, so you can jump straight to Group 30 Schematics without flipping through 750 pages by hand.
