Abstract
A controller for detecting an unwanted object in an agricultural machine. The agricultural machine includes a pair of rollers for receiving crop material therebetween. The pair of rollers define a variable roller opening therebetween. The controller is configured to: receive a roller-opening-value that is representative of the size of the roller opening; determine a strength-value based on the roller-opening-value and a roller-speed-value, wherein the roller-speed-value is representative of the rate of change of the roller-opening-value, with respect to time; compare the strength-value with a threshold-value; and if the strength-value exceeds the threshold-value, then provide an output signal that is indicative of an unwanted object being detected.
