1. A soil processing roller comprising:
a roller shell elongated in the direction of a roller axis of rotation and rotating about the roller axis of rotation during a soil processing operation,
a first fluid chamber in a roller interior space delimited by the roller shell, wherein, in association with the first fluid chamber in an axial end region of the roller interior space, a first opening group comprising a first filling opening, a first discharge opening and a first fill level control opening is provided,
a shielding element disposed in the axial end portion of the roller interior space and not rotating about the roller axis of rotation during a soil processing operation, wherein a first release recess is provided in the shielding element,
wherein a second fluid chamber, substantially separated from the first fluid chamber against fluid exchange, in the roller interior space delimited by the roller shell, wherein, in association with the second fluid chamber in the axial end region of the roller interior space, a second opening group comprising a second filling opening, a second discharge opening and a second fill level control opening is provided,
and in that:
in a first rotational positioning of the soil processing roller about the roller axis of rotation, the first discharge opening and the first fill level control opening are positioned in the circumferential direction in the region of the first release recess, and the second discharge opening and the second fill level control opening are covered by the shielding element,
in a second rotational positioning of the soil processing roller about the roller axis of rotation, the second discharge opening and the second fill level control opening are positioned in the circumferential direction in the region of the first release recess and the first discharge opening and the first fill level control opening are covered by the shielding element.
