Abstract:
A chopper assembly for a combine includes a rotary chopper element, a chopper grate assembly spaced from the rotary chopper element to form a passageway for crop residue and a knife bank adjustably connected to the chopper grate assembly. The knife bank is movable between a first position where the knife bank is fully inserted into the passageway and a second position where the knife bank is full retracted from the passageway. An actuating mechanism is used to move the knife bank between the first position and the second position. A position sensor is used to measure the position of the actuating mechanism and determine the position of the knife bank relative to the passageway.
