![John Deere 5036C, 5039C, 5041C, 5042C Repair Manual [Tractors]](https://youfixthis.com/wp-content/uploads/2012/02/Manual_Download-300x300.jpg)
Part of the John Deere Repair Manuals.
This is the factory diagnostic manual (TM-series) for the 2013-2021 John Deere 6M tractors: 6105M, 6115M, 6125M, 6130M, 6140M, 6150M and 6170M in one book. It is the fault-finding half of the documentation - full DTC tables for all seven models, symptom-based diagnosis for no-code problems, functional and diagnostic wiring schematics, ECU pin-outs, connector views and harness routing. Hydraulic and transmission sections carry real test values: PC low-pressure circuit max 1750 kPa, PFC 2300 kPa, high-pressure circuit 21000 kPa, SCV operational checks at 40 degrees C oil temperature. PowrQuad, PowrReverser and SyncroPlus are all covered. These are Final Tier 4 machines with DPF and CAN bus, so this book earns its keep fast.
Complete the set for your 6105M-6170M
