An agricultural harvester includes a chassis and a residue handling system carried by the chassis. The residue handling system includes a set of rotating knives disposed in a housing, a first set of counter-knives, and a residue pivoting platform and/or a second set of counter-knives. Crop residue travels through the system in a residue flow direction. The first set of counter-knives are configured to enter the housing proximate to the set of rotating knives. The residue pivoting platform is positioned proximate to the first set of counter-knives in an upstream direction relative to the crop residue flow direction. The second set of counter-knives are configured to enter the housing proximate to the set of rotating knives. The second set of counter-knives are in a downstream direction relative to the crop residue flow from at least one of the residue pivoting platform and the first set of counter-knives.
