• and
• a spreader system for spreading the crop residue over a field, the spreader system comprising:
• a first spreader device including a plurality of first paddles configured to rotate about a first axis to define a first spread path;
• a second spreader device including a plurality of second paddles configured to rotate about a second axis to define a second spread path, the second spreader device and the first spreader device located side-by-side;
• a deflector including a first deflector portion for deflecting the first spread path and a second deflector portion for deflecting the second spread path;
• and
• a deflector driver connected to the deflector,
