  • Harvester fan speed control based on yield
    Patent number: 9706709
    Abstract: A harvester having a harvesting structure for harvesting crop and a crop receptacle for receiving harvested crop. The harvester comprises a crop conveying fan configured to operate at a fan speed to facilitate transfer of harvested crop from the harvesting structure to the crop receptacle. A control system for controlling the fan speed based on crop mass flow comprises a crop mass flow feedback device that provides a crop mass flow feedback signal indicative of crop mass flow. A controller is in communication with the crop mass flow feedback device and is configured to automatically lower the fan speed when the crop mass flow feedback signal indicates a lower crop mass flow and automatically raise the fan speed when the crop mass flow feedback signal indicates a higher crop mass flow.
