Designed for High-Capacity Grain Harvesting

The 840CD and 880CF Draper Headers were developed for producers demanding higher harvesting capacity in cereals, soybeans, canola, wheat, and other small grain crops. Their draper feeding system transports crop material evenly toward the center feeder, reducing bunching while improving feeding consistency. Combined with a responsive hydraulic reel system and precision cutterbar, these headers help maintain excellent harvesting performance even under heavy crop conditions.
