A belt separating arrangement for a round baler includes a separating member positioned in a run of belts between a pair of spaced baler rollers. The separating member may be in the form of a separating roller with which each belt in a pair of adjacent belts is engaged in a different location, such that the separating member is operable to separate the belts to enable trash to fall into the crop inlet stream for incorporating into a baler. In one form, the separating arrangement includes a separating roll and an auxiliary roll, and each belt in a pair of adjacent belts is trained about the separating roll in a different location, as well as about the auxiliary roll. In another form, the separating arrangement is in the form of a sectioned separating roll, which includes a series of side-by-side roller sections mounted to a shaft such that each roller section can rotate in either direction. Adjacent belts are engaged with the roller sections on opposite sides of an axis of rotation defined by the shaft, to provide a space through which trash adhering to the belts can fall.
