Part of the New Holland Repair Manuals.
When the side draper walks off its rollers with dry wheat standing, the fix is the New Holland 840CD, 880CF service manual PDF: 427 pages of factory data for both draper header variants, OEM ID 47730915. Hydraulic schematics trace the reel vertical and fore-and-aft positioning circuits through the main control valve, and wiring diagrams map every harness and connector behind header leveling, reel speed, and the feeding control system. Attachment sections take up nearly half the book, running from reel removal and tine pitch adjustment through cutterbar rebuilds, retractable finger assemblies, and draper belt tracking. Set auger flighting 24 mm (0.9 in) off the header floor, hold knife head clearance at 2 mm, and torque the knife arm bolts to 136 N·m (100 lb ft). A half-stripped cutterbar is no place to hunt one number. Bookmarked and searchable by keyword, this PDF hands you that spec and gets your header cutting again.
