An ejector system (1) for ejecting bales from a bale-forming chamber (11) of an agricultural baler comprises a first (2) and second (3) shuttle assembly. The first shuttle assembly (2) reciprocates when being driven. The first shuttle assembly (2) is adapted for establishing mechanical contact with the second shuttle assembly (3) and for driving the second shuttle assembly (3) during movements of the first shuttle assembly (2) in a reverse direction (D) substantially opposite to the forward direction (D) of the bales in the bale-forming chamber (11), thus synchronizing reverse movement of both shuttle assemblies (2, 3).
