Abstract: A round baler having a main frame, a tailgate pivotally connected to the main frame and an apron extending around a plurality of guide rolls disposed in the main frame and the tailgate. A pair of take up arms, rotatably mounted on the main frame, carry at least one additional guide roll for the apron. A bale forming chamber, including the apron, varies in size from a bale starting position to a full bale position. A trash baffle is provided for preventing trash from entering the area between the belts and one or more of the rolls as the bale is being formed in the bale forming chamber. An auxiliary trash baffle is also provided for preventing trash from entering the area between the belts and one or more of the rolls under conditions where the belts are moving in the direction opposite to the direction of travel during bale formation.
