Chopper with movable outlet floor ramp

A chopper for an agricultural harvester, comprising:

• a housing, the housing comprising a variable geometry outlet floor, a rotor positioned in an interior region of the housing for rotation therein relative to the housing,
• a bank of counter-knives, the rotor comprising blades that interact with the bank of counter-knives to chop crop residue upon rotation of the rotor in a chopping direction, the bank of counter-knives movable relative to the rotor between a first aggressiveness position and a second aggressiveness position to adjust a chopping aggressiveness of the chopper with the chopping aggressiveness being greater when the bank of counter-knives is positioned in the first aggressiveness position than in the second aggressiveness position, the outlet floor comprising a ramp positioned downstream from the bank of counter-knives relative to the chopping direction and movable relative to the rotor between a first ramp position and a second ramp position to manage a trajectory of crop residue relative to a residue spreader of the agricultural harvester, the ramp raised more into the interior region in the second ramp position than in the first ramp position, and
• an adjuster in communication with the bank of counter-knives and the ramp to position the ramp in the first ramp position when the bank of counter-knives is positioned in the first aggressiveness position and to position the ramp in the second ramp position when the bank of counter-knives is positioned in the second aggressiveness position,
• wherein the adjuster comprises a knife actuator to move the bank of counter-knives between the first and second aggressiveness positions and a ramp actuator to position the ramp in the first ramp position when the knife actuator positions the bank of counter-knives in the first aggressiveness position and to position the ramp in the second ramp position when the knife actuator positions the bank of counter-knives in the second aggressiveness position, the knife actuator comprises a rotatable shaft, the ramp actuator comprises a linkage coupled to the rotatable shaft and the ramp to move the ramp in response to rotation of the rotatable shaft, the outlet floor comprises a fixed portion, and the ramp is coupled to the fixed portion for pivotable movement between the first ramp position and the second ramp position in response to operation of the linkage due to rotation of the shaft.
