New Holland 840CD, 880CF Draper Header PDF Repair Service Manual (Publication No. 47730915)

High-capacity combines can only perform at their best when the header delivers a smooth, uninterrupted crop flow. The New Holland 840CD and 880CF Draper Headers are designed to maximize harvesting efficiency by gently conveying crop from the cutterbar to the feeder housing, reducing grain loss while maintaining a consistent feed rate in cereals, soybeans, canola and pulse crops. Because these headers rely on synchronized draper belts, hydraulic reel controls and precision cutterbar components, accurate factory repair procedures are essential whenever major servicing or component replacement is required.

This OEM Factory Repair Service Manual (Publication No. 47730915) provides dealership-level workshop information for the New Holland 840CD and 880CF Draper Headers. It contains complete repair instructions covering cutterbar overhaul, draper belt servicing, hydraulic diagnostics, reel adjustments, gearbox repairs, electrical troubleshooting and detailed inspection procedures, allowing technicians to restore original harvesting performance using official New Holland specifications.

Designed for Gentle Crop Handling and Maximum Feeding Efficiency

The 840CD and 880CF are flexible draper headers engineered to maintain close ground contact while delivering crops evenly into the combine. Depending on configuration, these headers are available in working widths of approximately 40 ft (12.2 m) and 45 ft (13.7 m), utilizing a flexible cutterbar, full-width center draper, side draper belts and hydraulically controlled reel system. Their design minimizes crop shatter while improving feeding consistency across varying field conditions, making proper servicing of the cutting and conveying systems especially important during harvest.
