Part of the New Holland Repair Manuals.
This is the factory repair manual for the New Holland CX700 and CX800 series combines. It works through the machine the way New Holland numbers it, then follows the crop path through product feeding, threshing, separation, cleaning and grain storage. The engine section gives the full specifications and wear limits for the 6-cylinder 7500 cc diesel, and the electrical section is by far the largest, running from page 1020 to page 3190 across sixteen chapters of circuits, control systems, diagnostics and schematics.
