A suspension device of an agricultural machine is intended for the mounting and elastic bearing of an implement, with a pivot arm carrying the implement, which pivot arm is elastically or pivotably mounted by means of at least one bearing section at a flange tube, which flange tube extends transversely to the work direction, with the bearing section surrounding the flange tube circumferentially and approximately coaxially, and with at least one elastic bearing element positioned between the bearing section and the section of the flange tube surrounded thereby, which elastic bearing element extends with its longitudinal axis essentially parallel to the pivoting axis of the pivot arm and to the longitudinal axis of the flange tube. Lateral support of the suspension device is provided by a guide element is on the suspension device having at least one guide surface for the lateral support and guidance of the implement.
