Abstract: A system for removing plant material from harvested crops includes a pinch roller conveyor including pairs of rotatable pinch rollers whose longitudinal axes are aligned with a length of the conveyor, the pinch rollers forming nips in which plant material can be caught and pulled down through the conveyor as the pinch rollers rotate, wherein first ends of the pinch rollers are laterally displaceable so that the pinch rollers can laterally separate from each other to facilitate passage of plant material.
