Part of the New Holland Repair Manuals.
When the reel drops out of position halfway through a lodged wheat field, the fix has to come from you, not a dealer an hour away. That is what this 353-page New Holland VariFeed 760CG service manual PDF is for: the factory workshop reference for the grain header, OEM ID 47705703. Hydraulic schematics trace the reel vertical and fore-and-aft positioning circuits plus the cutter control circuit, while wiring diagrams map the harnesses, feeding control system, and cab header controls pin by pin. Header work itself, reel, cutting mechanism, feed auger, frame, fills over a third of the book. Check the friction clutch is set at 1 000 N·m (737.6 lb ft), and meter a suspect height sensor against 1000 Ω ±20% before torquing its replacement to 1.35 N·m. It's just you, the header, and the weather window. Jump by bookmark to the circuit you need, or print the pages and let them get greasy on the bench.
