Soil processing roller and method for operating a soil processing roller

A soil processing roller for a soil processing machine, comprising a roller shell which is elongated in the direction of a roller axis of rotation and surrounds a roller interior and an unbalanced arrangement which is arranged at least partially in the roller interior, wherein the unbalanced arrangement comprises at least one unbalanced mass rotatable around an unbalanced axis of rotation having center of mass eccentric to the unbalanced axis of rotation and an unbalanced drive system having at least one unbalanced electric drive motor for driving the at least one unbalanced mass to rotate around the unbalanced axis of rotation, wherein the at least one unbalanced mass is in an idle position when the unbalanced arrangement is deactivated, wherein in the idle position, the center of mass of the at least one unbalanced mass is positioned vertically below the unbalanced axis of rotation in a vertical direction, wherein the unbalanced drive system is configured, upon deactivation of the unbalanced arrangement, to operate the at least one unbalanced electric drive motor in an unbalanced return phase in such a way that the at least one unbalanced mass is moved into the idle position, wherein the unbalanced drive system is configured to move the at least one unbalanced mass from a deflected position into the idle position in the unbalanced return phase, wherein in the deflection position, the center of mass of the at least one unbalanced mass is deflected at a deflection angle from the idle position, wherein the unbalanced drive system is configured to operate the at least one unbalanced electric drive motor to generate a decreasing torque by subjecting the unbalanced electric drive motor to a voltage so as to lower an electric current conducted through the unbalanced electric drive motor in the unbalanced return phase for gradually moving the at least one unbalanced mass from the deflected position into the idle position.
