John Deere 6110J, 6125J, 6130J and 6145J Tractors Diagnostic Manual (TM801863, Spanish)

What's Covered in This Manual

This is the Diagnostic manual (TM801863) for the John Deere 6110J, 6125J, 6130J and 6145J tractors, and it's worth stating plainly up front: this edition is written entirely in Spanish, as published by John Deere's European office in Mannheim for Spanish-speaking markets. If you need an English edition, this isn't it - but for a Spanish-speaking technician in Europe, Latin America, or anywhere else, it's the genuine factory diagnostic reference for these four tractors, with the same depth of coverage as John Deere's English-language manuals for comparable models.

These tractors could be ordered with either the SyncroPlus or the PowrQuad transmission, and the manual's observed-symptoms section (Section 212) breaks out diagnostics separately for each. The BCU (Basic Control Unit) handles the electronic hitch control, PTO, differential lock, front-wheel drive, and brakes, and its diagnostic trouble codes get their own dedicated section - with the electronic hitch control procedures specifically split between the 6110J/6125J/6130J group and the 6145J, since that model's hitch control setup differs from the other three.

Past the BCU diagnostics, the manual covers the engine, electrical system (also split by whether the tractor has an open operator station or a cab), transmission, drive train, steering and brakes, hydraulic system, and operator's cab, each with theory of operation, test procedures and wiring/connector references. At 1,094 pages, this is a comprehensive diagnostic manual for this four-model tractor line, provided you can read Spanish or are working with someone who can.
