<p>The machine has a supply device for feeding crop to a crop processing device, and a controller (66) for generating an output signal based on detected rotational speed of the processing device and/or the supply device. The controller is connected with a set of sensors (68, 70) that detect rotational speed of the supply device and/or the processing device or rotational speed of elements standing in drive connection with the processing device. The controller stores the rotational speeds detected by the sensors for accessing the sensors during failure of one of the sensors.</p> |
