The device for carrying out an agricultural operation, and in particular working vegetation located on the ground, comprises a shaft part (5) connected to the frame (1), an element (3) of the fold-up device, which element is fastened to the side panel (2) and has a slot (4) which is substantially vertical in the transport position, which slot is rotatable about the shaft part and is positioned in such a way with respect to the shaft part that the side panel is downwardly displaceable along the shaft part after folding-up. Furthermore, working devices 8 are protected in the transport position by the side panel. The advantage of the device is that the distribution of weight of the side panel is changed, and the risk of wobbling is limited to a greater extent as the agricultural device moves in the transport position. The weight moves closer to the hinge point (rotation point), so that the moment of the weight is effectively reduced.
