摘要：
A work vehicle for working a swath of crop has at least one ground-engaging wheel or track mounted to the work vehicle and movable in a travel direction along a tread path. A first redistribution device is mounted to the work vehicle to move crop that is ahead of the at least one ground-engaging wheel or track relative to the travel direction. A second redistribution device is mounted to the work vehicle to move crop that is behind the at least one ground-engaging wheel or track relative to the travel direction. The first redistribution device is configured to open the swath of crop along substantially only the tread path ahead of the at least one ground-engaging wheel or track relative to the travel direction, and the second redistribution device is configured to close the swath of crop along the tread path behind the at least one ground-engaging wheel or track relative to the travel direction.
