Abstract
A ground processing roller includes a roller shell rotatable about a roller axis, a first lubricant sump arranged in a height direction below the roller axis, a second lubricant sump arranged in the height direction below the roller axis, and an overflow connection between the first lubricant sump and the second lubricant sump. Lubricant can flow from the second lubricant sump via the overflow connection into the first lubricant sump when the second lubricant sump level is reached or exceeded. The first lubricant sump is filled or fillable with lubricant up to a first lubricant sump level having a first distance from the roller axis in the height direction. The second lubricant sump is filled or fillable with lubricant up to a second lubricant sump level having a second distance from the roller axis in the height direction. The second distance is smaller than the first distance.
