Systems and method for forming a stable silo face in bulk material are disclosed. Particularly, systems and methods for forming a negative rake angle in a silo face of bulk silage are disclosed. Rotation of an articulated arm (e.g., raising and lowering), altering a length of the articulated arm (e.g., extension or retraction), and movement of a machine relative to the silo face (towards and away from) may be automatically controlled to form the negative rake angle. Different implementations contemplate automated control of all or fewer than all of these operations.
