The device has a harrow pivotal arm (2) pivotable around a pivotal axis (1) that extends transverse to a moving direction (F). The pivotal axis and a harrow element (3) are arranged at a front end (2v) and a rear end (2h) of the harrow pivotal arm in the moving direction, respectively. Control units comprise a single drive unit (4) for infinitely pivoting the harrow pivotal arm or multiple harrow pivotal arms around the pivot axis. A control rod is rotatable around a rotational axis that runs transverse to the moving direction. The harrow pivotal arm comprises a return suspension. An independent claim is also included for an agricultural cultivation device.
