Patent ID: 7872587

Claim:
A control system for an agricultural harvesting machine having a crop processing system, a control panel for enabling an operator of the harvesting machine to set a plurality of operating parameters of the crop processing system that affect the harvesting performance, and a plurality of sensors for determining prevailing values of crop quality parameters, wherein the control system comprises a data processor having a display for communicating information visually to the operator, the control system being operative to determine when a crop quality parameter exceeds an unacceptability threshold, and, following such determination of the crop quality parameter, to display to the operator an operating parameter of which adjustment is recommended in order to restore the crop quality parameter to an acceptable value, the recommended operating parameter being derived from data stored in a look-up table within the data processor, wherein the look-up table includes for each crop quality parameter default settings of a group of operating parameters by which the crop quality parameter is affected, when an acceptability threshold is exceeded, the prevailing values of the different operating parameters associated with the determined crop quality parameter, are compared by the data processor with the default settings thereby resulting in a plurality of difference values, the plurality of difference values are compared with one another, wherein the data processor selects the operating parameter from the group of operating parameters having the largest difference value and displays the operating parameter with a recommended corrective action.
