John Deere's TM1679 runs 722 pages on the 4500, 4600, and 4700 Compact Utility Tractors, working from the diesel engine through the final drive and PTO. Electrical coverage includes schematics across both North American and European wiring layouts; the hydraulic schematics trace fluid all the way through the hydrostatic circuit, and the troubleshooting charts reach into steering and brakes. Repair procedures run deep, with exploded views across all three power train builds: gear, hydrostatic, and PowerReverser. The torque numbers are spelled out too, including cylinder head bolts at 85-91 N•m (62-67 lb-ft) with oil applied and front and rear wheel bolts at 88-108 N•m (65-80 lb-ft). When the tractor is down, that beats guessing on a forum. Open it on a phone or tablet, jump by bookmark, and get back to the repair.

John Deere 4500, 4600, 4700 Common Problems This Manual Covers
A 4500, 4600, or 4700 that sputters, bogs down under load, or won't start is usually starved for fuel. p. 11
Inspect the fuel filter and lines for restrictions, then drain the tank and refill with clean diesel to the rated capacity (47.3 L (12.5 gal) for 4500, 4600 Hydrostatic Drive, and 4700 Hydrostatic Drive; 37.9 L (10.0 gal) for 4600 PRT and 4700 PRT), listed on pages 11, 14, and 15. Test cylinder compression against the 3233 ± 97 kPa (469 ± 14 psi) spec.
Manual Section: Engine System DiagnosisThe temperature gauge climbs into the red, or the engine keeps overheating even after the grille has been cleaned. p. 33
Check the radiator cap valve opening pressure and verify it holds 88.3 ± 14.7 kPa (12.8 ± 2.2 psi). Pull the thermostat and test it in a water bath, confirming it opens at 69.5 - 72.5° C (157 - 163° F) as specified on page 33.
Manual Section: Engine System DiagnosisThe tractor loses motion, responds poorly through the hydrostat, or won't move under a heavy load. p. 93
Verify hydrostatic transmission fluid levels before reading any system pressures. Test the hydrostatic pump pressure relief valve setting and confirm it reaches 41368 kPa (6000 psi) as detailed on page 93. Inspect the filter and control linkages for physical damage or excessive wear.
Manual Section: Hydrostatic Power Train TroubleshootingSafety interlock test fails during startup checks or the engine turns over slowly in cold weather. p. 207
Measure battery voltage at the terminals to confirm a minimum of 12.4 VDC as shown on page 207. Inspect the seat switch, brake interlock, and PTO switch for continuity. Clean all ground connections and replace the battery if it fails a standard load test.
Manual Section: Electrical Cranking Circuit DiagnosisFrequently Asked Questions
What are the torque specs for the cylinder head on a John Deere 4600/4700?
Cylinder head bolts on the 4500, 4600, and 4700 torque to 85 - 91 N•m (62 - 67 lb-ft). Dip them in clean engine oil first, then bring them up in three stages of increasing torque.
What are the replacement specifications for fuel filter?
The replacement unit is a "Clear Bowl Water Separator with Disposable Paper Element, Water Floating Red Ring." When you swap it, renew the O-rings and the filter element, and seat the spring correctly in the filter cover.
