Abstract: A driveshaft for driving agricultural machinery has two profiled tubes which are movable one inside the other and serve to transmit torque. Two protective tubes (5, 6) are provided which are also axially movable one inside the other. To be able to lubricate the profiled tubes, a maintenance aperture is provided which, at a certain driveshaft length, is obtained as a result of the overlapping position of two apertures (11, 12) in the protective tubes (5, 6). However, when not used, the aperture (11) in the outer protective tube (6) is covered by a closing sleeve (9). When extending the driveshaft after moving the closing sleeve (9), for the purpose of providing access to the apertures, the closing sleeve (9) is automatically returned into the closed position by a cam (13). This design measure results in a higher degree of safety by ensuring that the apertures are always closed when the driveshaft is in operation.
