The chopper assembly includes at least one movable chopping knife; a plurality of counter knives movable between a first knife position and a second knife position, the plurality of counter knives configured to cooperate with the at least one chopping knife to cut crop material when in the first knife position; a shear bar movable between a first bar position and a second bar position; and a linkage assembly connected to the plurality of counter knives and the shear bar such that the linkage assembly is selectively actuable to simultaneously move the plurality of counter knives and the shear bar between their respective first and second positions.
