Part of the John Deere Repair Manuals.
This is the John Deere TM1679 Technical Manual for the 4500, 4600, and 4700 Compact Utility Tractors, the same 722 page service manual John Deere wrote for its own technicians. It covers tractors built across the serial ranges listed for each model, from the 4500 through the 4700.
Inside you get the full repair picture: the 4TNE84 and 4TNE88 diesel engines, the gear, hydrostatic, and PowrReverser power trains, final drives and PTO, plus electrical (North American and European sections), steering, brakes, and hydraulics. Every system is grouped together with specifications, component locations, theory of operation, troubleshooting charts, diagnostics, tests and adjustments, and step by step repair.
With torque values, fluid capacities, and pressure settings taken straight from Deere, you can diagnose a fault, set clearances, and rebuild a component yourself instead of guessing or paying shop rates. It is delivered as a downloadable PDF you can read on screen or print.
