Engineered to Recover Every Windrow

Unlike conventional grain headers, the 790CP is dedicated to lifting pre-cut crops cleanly from the field while preserving grain quality.

The adjustable floating pickup and efficient crop transfer system help maintain uniform feeding while reducing plugging in heavy windrows.
