New Holland CX720, CX740, CX760, CX780, CX820, CX840, CX860 & CX880 Combine PDF Repair Service Manual (Publication No. 6043400100)

Efficient grain harvesting depends on a combine that can maintain consistent crop flow, deliver excellent grain quality and minimize harvesting losses under changing field conditions. The New Holland CX720, CX740, CX760, CX780, CX820, CX840, CX860 and CX880 Combines were developed for professional harvesting operations, combining high-capacity crop intake, advanced threshing technology, efficient straw separation and powerful grain cleaning systems. These combines are designed for cereals, oilseeds and other high-yield crops while maintaining productivity throughout long harvesting seasons.

Continuous harvesting places heavy loads on the feeder housing, threshing drum, concaves, straw walkers, cleaning shoe, unloading augers, hydrostatic drive system and hydraulic circuits. Accurate repairs require official workshop procedures instead of replacing expensive components through trial and error. This OEM Factory Repair Service Manual provides dealership-level repair information for the New Holland CX720, CX740, CX760, CX780, CX820, CX840, CX860 and CX880 Combines. Publication 6043400100 includes complete diagnostics, inspection, overhaul, adjustment, calibration and operational testing using official New Holland service procedures.

Machine Overview

Built for Maximum Harvesting Efficiency

The CX Series combines are engineered to maintain smooth crop flow from the feeder housing through the threshing, separation and cleaning systems while reducing grain loss. Synchronization between the feeder chain, threshing cylinder, straw walkers, cleaning shoe and grain elevators is essential for peak harvesting performance. Regular servicing of these integrated systems helps maximize harvesting capacity while reducing downtime during critical harvest periods.

The factory repair manual follows the same service sequence used by authorized New Holland technicians, beginning with system diagnostics before progressing through complete component inspection, overhaul, calibration and operational testing.
