Agricultural baler including a bale chamber with a low traction rotary compression element

An agricultural baler comprising:

• a frame;
• a pick-up device;
• a cylindrical bale chamber;
• and
• a binding device that supplies a binding material for binding a bale formed in the bale chamber;
• wherein the bale chamber comprises:
• an inlet,
• two opposed side walls forming ends of the bale chamber,
• a set of rotary compression elements positioned within the bale chamber,
• drive means configured to drive rotary movement of the rotary compression elements,
• a front part and a rear part, each of the front and rear parts comprising approximately one half of the bale chamber, wherein the rear part is attached to the front part through a pivot joint so that the rear part can pivot between a closed condition for forming a bale in the bale chamber and an open condition for releasing a bale from the bale chamber, and
• wherein the set of rotary compression elements includes at least one low traction rotary compression element, which is located within a lower part of the bale chamber and is configured to provide a reduced level of traction to a bale in the bale chamber, as compared to a majority of the other rotary compression elements, at least when the rear part is in an open condition,
• wherein the at least one low traction rotary compression element includes a roller that is configured to rotate freely during opening of the rear part, and
• wherein drive means to the at least one low traction rotary compression element is configured to disengage during opening of the rear part, while a majority of the other compression elements keep turning.
