Part of the John Deere Repair Manuals.
This is the Diagnosis and Tests technical manual for John Deere 6110M, 6120M, 6125M, 6130M, 6135M, 6140M, 6145M, 6155M, 6175M and 6195M tractors, 2019-2024. These are heavily electronic machines - multiple control units talking over CAN bus - and when one throws a code, guessing gets expensive fast. This manual is the factory playbook for chasing those faults: diagnostic trouble code tables, step-by-step electrical and hydraulic test procedures, calibration routines, and system operation theory so you understand what you are testing. It covers engine, electrical, hydraulics, transmission diagnostics, cab systems and operational checks. If your 6M series tractor has a warning light on and the dealer wants a week just to look at it, this is the book that lets you do the looking yourself.
