摘要： An earth working roller for use in an earth working machine includes a roller drum, which extends in a direction along a roller axis of rotation, surrounds a roller interior, and has a circular outer circumferential contour, wherein a substrate breaking configuration is provided on the outer circumferential surface of the roller drum. The substrate breaking configuration includes a plurality of impact bars along the roller drum in the direction of the roller drum axis of rotation, as well as a plurality of breaker bars along the roller drum in a circumferential direction.
