The adjustment of operating parameters such as the sieve opening, concave opening, chaffer opening, rotor speed and/or fan speed is/are accomplished under the control of a microprocessor operating in response to the striking of keys on a keyboard. The combine harvester operator may select a particular parameter for adjustment by striking a key corresponding to that parameter. The desired setting of the selected parameter is then keyed into the keyboard and an ADJUST key struck to activate the adjustment process. Alternatively, the operator may strike a key corresponding to the crop to be harvested, a further key corresponding to the ambient moisture level of the crop, and then the ADJUST key. In this case the microprocessor reads from a stored table the values for adjusting all parameters so as to obtain a satisfactory sample and a maximum yield for the crop being harvested. The microprocessor sends signals to actuators for adjusting the various parameters and transducers sense the various parameters and provide information to the microprocessor for determining when the parameters have been adjusted to the selected values. A visual display is provided so that the operator may monitor the parameters and also observe entries keyed in at the keyboard.

In a combine harvester adjustment system having a plurality of actuator means for selectively adjusting a corresponding plurality of system operating parameters over ranges of values, the improvement comprising: a keyboard including a plurality of crop keys, one for selecting each of a plurality of crops; first means for producing a signal representing the moisture level of a crop to be harvested; memory means for storing sets of optimum operating values, there being one set of optimum operating values corresponding to each different combination of crop and moisture level with each set including an optimum operating value for each actuator means; a microprocessor responsive to said first means and to actuation of one of said crop keys for reading from said memory the corresponding set of operating values; and, output means responsive to said microprocessor and optimum operating values read from said memory for applying adjusting signals to said actuator means to adjust said operating parameters to said optimum operating values within the range of values for harvesting the selected crop. The method of adjusting operating parameters of a combine harvester automatically, said method comprising: storing sets of adjusting values, there being one set of adjusting values for each combination of a crop and a moisture level for that crop; each set of values including an adjusting value corresponding to each operating parameter; repetitively sensing said parameters to obtain the actual values thereof; selecting a crop and a moisture level to thereby select one of said sets of adjusting values; comparing the adjusting values in the selected one of said sets of adjusting values with said actual values; and, adjusting each operating parameter until the comparison between the actual value and adjusting value for that parameter indicates that the two are equal.
