Abstract: A brush device for brushing an animal, in particular the back, head and/or tail of the animal, such as a cow, includes a rotatable brush, as well as an electric drive motor, which is configured to supply a drive torque for rotatably driving the brush in at least one rotation direction. The drive torque supplied by the drive motor is set in such a manner that the brush can be turned back by means of muscular power of the animal and/or an individual counter to the driven rotation direction while said drive torque is being supplied by the drive motor.
