Part of the John Deere Repair Manuals.
This 743-page John Deere 6800, 6900 Technical Manual PDF (OEM #TM4516) puts both tractors' full factory service data in one place, covering engine through cab. You get the complete PowrQuad Module and Range Transmission rebuild sequence, front and rear PTO procedures, MFWD clutch service, and a full electrical section with charging circuits, starting motor circuits, and connector-level harness diagnostics. Open to exploded views across drive systems, step-by-step procedures for hydrostatic steering and wet disc brakes, and a dedicated special tools section listing adapters by part number. The 6800 puts out 88 kW (120 hp), the 6900 steps to 96 kW (130 hp); replace brake discs below 5.5 mm (0.216 in.) and torque the starter terminal 30 hex nut to 30 N-m (23 lb-ft).
