A round baler may include a frame supported by one or more ground engaging devices, a bale forming chamber including sidewalls spaced apart a distance defining a width of the bale forming chamber, a discharge gate selectively operable between a baling position and a discharge position, and a bale forming apparatus, which forms the round bale in the bale forming chamber. The round baler may include a first set of spacers positioned adjacent at least one of the sidewalls reducing the effective width of the bale forming chamber.
