An ejector system for a bale-forming chamber comprises a shuttle assembly having protrusions. This shuttle assembly is able to reciprocate to propel at least two bales towards a discharge outlet. The system furthermore comprises a tilting mechanism for tilting the shuttle assembly to retract a subset of the protrusions from an extended position projecting into the bale-forming chamber to a retracted position disposed outside the bale-forming chamber, thus, during movement of the shuttle assembly towards the discharge outlet, propelling only the bale present in the bale-forming chamber closest to the discharge outlet.
