The present invention relates to a motor vehicle carried warning device for safeguarding against injury to animals from the knife blades or like cutters of a cutting machine which is towed by or carried by the vehicle, such as a mowing machine having rotary cutters for cutting crops such as grass, hay or like pasture, said crops particularly being intended for ensilage. The device includes one or more IR-detectors (1) which register the movement and body heat of an animal located in front of the vehicle and send a first signal to an acoustic unit (2) which produces a sound, preferably a high frequency sound, which is frightening to the animal, and sends a second signal to an operating unit (6) in the driver's cabin of the vehicle, which activates another acoustic unit (3) which produces a sound that is audible to the human ear, and also a light unit (4), for instance an illuminating warning lamp, these units remaining activated for as long as an animal remains in front of the vehicle.

Dispositif d'avertissement porté par un véhicule et destiné à éviter que des animaux ne soient blessés par les lames ou couteaux d'une machine à couper remorquée ou portée par le véhicule, par exemple une tondeuse à couteaux rotatifs servant à couper les cultures telles que l'herbe, le foin ou tout fourrage analogue, ces cultures étant destinées notamment à l'ensilage. Le dispositif comporte un ou plusieurs détecteurs IR (1) pouvant détecter les mouvements et la chaleur animale d'un animal se trouvant devant le véhicule, et transmettre un premier signal à une unité acoustique (2) qui émet un son, de préférence à haute fréquence, susceptible d'effrayer l'animal, et transmet un second signal à une unité de commande (6) située dans la cabine de l'opérateur du véhicule et destinée à actionner une autre unité acoustique (3), qui émet un son audible par l'oreille de l'homme, ainsi qu'une unité lumineuse (4) telle qu'un témoin lumineux, ces unités demeurant à l'état actif aussi longtemps que l'animal se trouve devant le véhicule.
