Part of the New Holland Repair Manuals.
A baler that quits tying in the middle of a dry-hay window costs you more than twine. That is the failure this 1102-page New Holland BR740A repair manual PDF exists to prevent: factory publication 87606299, covering all four A-series round balers, BR740A through BR780A. Wiring diagrams trace the Bale Command Plus and Auto Wrap harnesses connector by connector, backed by component testing procedures that fill the better part of the electrical section, nearly a fifth of the book. Hydraulic schematics map the tailgate lift, belt tension, and pickup lift circuits, while overhaul coverage runs from the PTO driveline and gearbox through belts, rolls, and the sledge assembly. Set net wrapper brake pad clearance at 2 to 4 mm; pull wheel lug bolts to 156 N·m (115 ft.-lbs.). Guess, and you pay twice: the part, then the teardown. Bookmarked and keyword-searchable, this PDF is on your laptop in minutes, well before the weather turns.
