  • Self-propelled harvesting machine and operating method therefor
    Patent number: 7343262
    Abstract: A method of operating a self-propelled harvesting machine includes continuously separating a crop-material flow into a useful-material flow and a remaining-material flow, in a separating step of the machine, capturing at least a portion of the useful-material flow from the separating step in a measurement channel, weighing the useful material contained in the measurement chamber and determining a density based on a weight that was measured, and optimizing operational patrameters of the separating step based on the weight that was determined.
