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