Part of the John Deere Repair Manuals.
This is the complete John Deere factory Diagnosis and Tests service manual for nine 6030-series tractors: the 6130, 6230, 6330, 6430, 6530, 6534, 6630, 6830 and 6930. Across 3,661 pages it gives you every system test and diagnostic procedure a John Deere dealer technician uses to locate a fault without unnecessary teardown. The structure is deliberate: start with fault codes or observable symptoms, run the operational check, measure the test value, compare it to the printed specification, and then decide whether the component is at fault. That discipline covers the entire machine - from the CAN BUS and five ECU modules down through three transmission families, the full hydraulic circuit, fuel and cooling systems, electrical wiring, steering, brakes, and the operator cab.
Complete the set for your 6130, 6230, 6330…
