The invention provides a device for performing an agricultural operation, wherein the device comprises a frame (10) with a lifting actuator (12), a lifting hinge (22) and at least one sub-frame (14) with at least one crop processing element (20), and wherein the sub-frame (14) is displaceable by means of the lifting actuator (12) about the lifting hinge (22) between an operative position and a transport position, wherein at least the sub-frame (14) is pivotable about a break-out hinge (28, 28) from the operative position to a broken out position under the action of a break-out force, wherein the device further comprises a readjusting actuator (30), the break-out hinge (28, 28) being readjustable by means of the readjusting actuator (30) from a broken out hinge position belonging to the broken out position of the sub-frame (14) to an operative hinge position belonging to the operative position of the sub-frame (14), characterized in that the lifting actuator (12) and the readjusting actuator (30) are operatively coupled in such a way that, when the lifting actuator (12) is switched on, the readjusting actuator (30) is also switched on automatically. By means of such a coupling it is prevented more reliably and more frequently that a broken out position continues unnoticed or undesired, because at each lifting operation it is also possible to correct a broken out position, if any. Moreover, the transport position is better protectable against unintended movements as a result of breaking out.
