Tandem roller for compacting an underlying ground

A tandem roller to compact an underlying ground, comprising:

• a machine frame supported by a front compaction drum with respect to a direction of travel and a rear compaction drum with respect to the direction of travel, the rear compaction drum being spaced apart from the front compaction drum in a longitudinal machine direction;
• and
• an operator platform with a driver's seat oriented in the direction of travel, the driver's seat being displaceable by an adjusting device from an operating position at a center of the operator platform with respect to a horizontal extension of the operator platform transverse to the direction of travel in a direction of at least one side of the tandem roller transversely to the longitudinal machine direction to at least one defined first operating position and to at least one defined second operating position, the defined second operating position being spaced farther apart from the center of the operator platform than the defined first operating position, wherein, in the first and the second defined operating position of the driver's seat, an operator sitting in the driver's seat looks in each case in a direction of the direction of travel,
• wherein the tandem roller has at least first and second direction finding aids, the first and the second direction finding aids being arranged offset from each other in a projection to a common virtual horizontal plane, the first direction finding aid being associated with the defined first operating position and the second direction finding aid being associated with the defined second operating position, such that the first direction finding aid for the operator sitting in the driver's seat located in the first operating position and the second direction finding aid for the operator sitting in the driver's seat located in the second operating position each indicate a ground point in line-of-sight extension from the driver's seat, which, viewed parallel to the direction of travel, is in each case located in linear extension of an end-face ground contact point of an end face of the front compaction drum located at a front of the tandem roller in the direction of travel which is the end face that is located in a direction of the adjustment direction of the driver's seat from the defined first operating position in a direction of the second defined operating position of the driver's seat.
