Abstract: A system for identifying irregularities in behaviors of a non-human animal, the system comprising a processing circuitry configured to: provide a behavioral baseline including first information on regular behaviors of the non-human animal over a given period of time when no irregularities occur; obtain data on a series of consecutively identified behaviors of the non-human animal identified over a second period of time; perform an action upon the data not complying with the behavioral baseline, thereby indicating an irregularity in the non-human animal behavior.

Abstract: A method and a self-propelled forage harvester for determining the need for grinding chopping blades of a chopping device of the self-propelled forage harvester is disclosed. A monitoring device determines, such as cyclically, the state of wear of the chopping blades. The monitoring device comprises an input/output unit through which to enter or select a target state of the chopping blades to be produced by a grinding device as a target. The monitoring device generates, such as continuously, information depending on the target state and the determined state of wear, and causes an output on the input/output unit to visualize the extent to which the currently determined state of wear deviates from the target state.
