Part of the John Deere Repair Manuals.
This is the complete John Deere factory repair manual (TM4787) for the 5620, 5720 and 5820 tractors. Across 1,152 pages it covers every system on the machine: the 4045 four-cylinder turbocharged diesel and its fuel, air, cooling and exhaust systems; the PowrQuad and PowrQuad Plus transmissions; front-wheel drive clutch, differential, final drives and PTO; hydrostatic steering and brakes; the full hydraulic system including pump, valves, selective control valves and hitch; a detailed electrical section with wiring harness routing, charging circuit and monitoring systems; and the operator cab. Torque values, test pressures and special tool references are called out where they matter so a repair is done to spec the first time.
