A crop loss level generator receives a crop loss sensor signal from a crop loss sensor and generates a crop loss metric indicative of a sensed crop loss level based on the crop loss sensor signal. A first crop loss display generator generates a first crop loss display element based on the crop loss metric and controls a display device to display the first crop loss display element relative to a target loss range indicator indicative of a target loss range. A historic crop loss display generator generates a historic crop loss display element, based on previously generated crop loss metrics, and controls the display device to display the historic crop loss display element relative to the target loss indicator and relative to the first crop loss display element.
