Abstract: The invention relates to a scraper device for a disc of an agricultural machine comprising:
a first outer scraper element comprising a suitable first scraper portion intended to rest against the outer surface of the first disc and a suitable first coupling portion intended to be coupled to a chassis of the agricultural machine; a first inner scraper element comprising a suitable second scraper portion intended to rest against the inner surface of the first disc and a suitable second coupling portion intended to be coupled to the first coupling portion of the first outer scraper element; the first inner scraper element being swivel-mounted with respect to the first outer scraper element around a second rotation axis; characterized in that it comprises: a resetting means connected to the second coupling portion to cause a rotational movement of the first inner scraper element along the second rotation axis, so as to press the second scraper portion against the inner surface of the first disc and so as to cause a rotational movement of the first outer scraper element along the first rotation axis to press the first scraper portion against the outer surface of the first disc.
