1. A square baler having a bale case within which crop is compacted by a plunger, a discharge outlet at one end of the bale case and an ejector system for advancing bales towards the discharge outlet independently of the movement of the compacting plunger, the ejector system comprising: a first shuttle assembly mounted in a wall of the bale case and having a first reciprocating elongate member configured for reciprocation parallel to a direction of movement of bales in the bale case; at least one dog mounted on the first reciprocating elongate member of the shuttle assembly to engage in a last bale in the bale case positioned nearest the discharge outlet and configured to advance the bale incrementally out of the discharge outlet in response to reciprocation of the first reciprocating elongate member of the first shuttle assembly; and a second shuttle assembly mounted in a wall of the bale case and having a second reciprocating elongate member configured for reciprocation independently of the first shuttle assembly, the second shuttle assembly having at least one dog mounted to the second reciprocating elongate member of the second shuttle assembly to engage in a next-to-last bale in the bale case and configured to advance the bale towards the outlet in response to reciprocation of the second reciprocating elongate member of the second shuttle assembly, wherein the first reciprocating elongate member and the at least one attached dog of the first shuttle assembly are movable with respect to the second reciprocating elongate member and at least one dog of the second shuttle assembly.
