Round baler and method for operating a round baler

A round baler comprising:

• a baling chamber positioned in a housing and having a variable diameter;
• a rotating pressing device configured to bound the baling chamber, the pressing device including one or more rollers configured to perform one or both of drive or guide the pressing device, with a first clamping arm pivotably mounted on a side of the housing and including at least one of the one or more rollers on a bailing chamber side for guiding a loop, and with a second clamping arm pivotably mounted on the side of the housing and having at least one roller at a free end that is configured to guide the pressing device;
• one or more hydraulically-actuated actuators configured to adjust a position of the first clamping arm and the second clamping arm in order for the first clamping arm and the second clamping arm to generate a compaction pressure with which the pressing device is configured to form a round bale;
• and
• a control unit in communication with the one or more hydraulically-actuated actuators and configured to:
• access at least one compaction power curve;
• access one or both of one or more operating parameters or one or more environmental parameters;
• and
• automatically control, using the at least one compaction power curve, the one or more hydraulically-actuated actuators to adjust at least one of the first clamping arm or the second clamping arm, by taking into account the one or more operating parameters that affect one or both of the at least one compaction power curve or the one or more environmental parameters of the round baler in order to maintain a substantially stable operating point during a shaping process of the round bale in which compaction power and drive power are substantially equal.
