Case IH Introduces Higher-Capacity Corn Headers

Farmers seeking higher harvesting capacity, lower mechanical stress and better residue handling increasingly rely on corn headers engineered for compatibility with high-output combines. The Case IH C500 series is designed to meet these requirements for operations using 75-cm row spacing, particularly those running the latest Axial-Flow and AF models.

Expanded Header Range for European Conditions
The series now includes the C516-75, the brand’s first 16-row corn header with 75-cm spacing offered in Europe. In addition to the existing 12-row C512-75, this larger configuration supports farms aiming to increase throughput without exceeding combine load limits. A key engineering change is the reduced overall weight of the picking units, which helps limit stress on the feeder, driveline and front axle while enabling the header to remain within the operating envelope of current AF combines.

Maintenance demands have also been streamlined through simplified access points, reducing downtime and maintaining field efficiency during long harvest windows—an important operational factor for European growers managing narrow harvesting periods.

Feeding Efficiency and Operator Control
C500 headers incorporate dual-action deck plates that can be adjusted hydraulically from the cab. This provides controlled ear retention and minimal header loss when crop moisture and ear size vary throughout the season.

One of the core performance features of the series is its large-diameter cross auger. With a 60-cm flight diameter and a 62.5-cm pitch, the auger is designed to deliver consistent feeding and minimize bunching across a range of crop volumes. These dimensions align with accepted engineering principles: larger diameters improve torque handling, while appropriate pitch ensures smooth transition of material into the feeder house.




Power Distribution and Component Protection
A dual driveline architecture separates the drives for the row units and the integral chopper. By isolating these loads, the system helps distribute torque more evenly and reduces peak stresses on gearboxes—a validated method in high-capacity header design. Overload protection is enhanced through dedicated slip clutches for each subsystem.

The series also integrates a monitoring system using sensors on the main toolbar to detect slip-clutch engagement in both the chopper and row units via vibration and frequency data. When triggered, the operator receives an immediate in-cab alert, allowing rapid response before component temperatures or loads escalate.

Designed to Maximize Output with AF Combines
The new C500 models are positioned for users aiming to optimize output from large Axial-Flow and AF combines using 75-cm rows. Their combination of reduced weight, improved feeding and automated monitoring supports both harvesting performance and long-term equipment longevity, contributing to lower operating costs across the harvesting season.
