The invention relates to a tedding machine comprising a frame (2) and two groups (18, 19) of plant-processing members (20) attached to the frame and a work frame (40), wherein the work frame comprises a carrying shaft (34) and is configured to move the groups from an operating position to a folded-up position, wherein the tedding machine can be brought to a transport position in which each group is mounted to the frame so as to be pivotable from an operating position to a folded-up position, and wherein the work frame comprises a pivoting device with a respective vertical pivot pin (35), in such a way that the groups can be brought from the folded- up position to the transport position by pivoting about the vertical shaft, and wherein the vertical shaft is connected to the horizontal carrying shaft and is situated between the upward rotation shaft of the inner plant-processing member of a group and the centre line of the frame.
