The invention relates to a pick-up device (1) comprising a rotary part (2) provided with at least one supporting arm (6) having raking and removal tools attached thereto, said at least one supporting arm (6) being able to pivot about an axis of rotation (9) in relation to the aforementioned rotary part (2) by means of at least a first bearing (A) and a second bearing (B), said at least first and second bearings (A, B) each comprising an outer ring (10) secured to the rotary part (2) and the supporting arm (6) can pivot about the axis of rotation (9) in relation to said outer ring (10). The invention is characterised in that: at least the first bearing (A) comprises an inner ring (12)； the inner ring (12) can pivot in relation to the outer ring (10) about the axis of rotation (9)； the inner ring (12) is secured to the supporting arm (6)； a stop means (13) connects the inner ring (12) to the outer ring (10)； and the stop means (13) limits the movement of the supporting arm (6) in relation to the rotary part (2) in a direction substantially parallel to the axis of rotation (9) to either a low or zero value. The invention also relates to an agricultural machine (33) provided with such a pick-up device (1).La présente invention se rapporte à un dispositif de ramassage (1) qui comprend une partie tournante (2) munie d'au moins un bras sup¬ port (6) auquel sont attachés des outils de râtelage et de prélève¬ ment, ledit au moins un bras support (6) pouvant pivoter autour d'un axe de rotation (9) par rapport à ladite partie tournante (2) au moyen d'au moins un premier palier (A) et un deuxième palier (B), lesdits au moins premier et deuxième paliers (A, B) comprenant chacun une bague extérieure solidaire (10) de ladite partie tournante (2) et par rapport à laquelle bague extérieure (10) ledit bras support (6) peut pi¬ voter autour dudit axe de rotation (9). Elle est remarquable en ce qu'au moins ledit premier palier (A) com¬ prend une bague intérieure (12), que ladite bague
