Part of the John Deere Repair Manuals.
This is the factory Diagnostic Technical Manual for the John Deere 5076E, 5076EL, 5082E, 5090E, 5090EL and 5090EH utility tractors, 2020-2024. These are electronic Final Tier 4 machines, and this book is built for chasing problems on them: full diagnostic trouble code lists for the CCU, ICC and PTR control units with retrieval and clearing steps, observable-symptom charts, wiring schematics with harness routing, and real test numbers for hydraulics, steering, brakes, SyncShuttle and PowrReverser transmissions, MFWD and differential lock. Every test spec is printed, down to pump flow rates and relief valve pressures. One thing to know up front: this is the Diagnosis and Tests book, not the component teardown manual. You find the fault here, then fix it.
Complete the set for your 5076E, 5076EL, 5082E…
