Engineered for Powerful Kernel Crushing and Crop Conditioning

Choose between the Ultimate250™ KP and XStream305™ KP advanced kernel processors that are designed to crush corn kernels and condition crop material for higher-quality silage. Both systems increase processing surface area and optimize crop flow to improve feed value and consistency.

Ground Speed Automation

Say goodbye to constantly adjusting your speed according to field conditions. Ground Speed Automation automatically adjusts harvester speed and engine RPM according to your preset limits on engine load. Automatically optimizing your speed helps to reduce fuel use and improve productivity.
