The working machine with an exchangeable superstructure (2) has an undercarriage (1) and a frame (14), on which the superstructure (2) is fastened releasably. Furthermore, a drive connection (10, 11) from a power take-off shaft (9) to a working appliance (53) on the superstructure (2) is provided. In order, when the superstructure (2) is exchanged, to guarantee the uncoupling or coupling of the cardan shaft (11) from or to the power take-off shaft (9) simultaneously and automatically, the cardan shaft (11) is provided as a sliding cardan shaft, the front joint of which is mounted so as to be resiliently pivotable and so as to be vertically displaceable to a limited extent. <IMAGE>
