Part of the New Holland Repair Manuals.
This is the factory service manual for the New Holland TC5.80, TC5.90 and TC5.90 Hillside combines, Tier 4B, part number 48001074. It works through the machine the way New Holland builds it, then follows the crop path from header attachment through feeding, threshing, separation, residue handling, cleaning and unloading. Read one thing before you diagnose the hydraulics: the machine carries two pumps without lateral flotation and three with it, so the circuit in front of you depends on how your combine was specified.
