Flex Packers are available in a 3-section configuration for widths of 21' to 32' . Packers 33' to 50' are built on a 5-section frame. The balanced frame design minimizes tongue weight. Each wing gang is independently suspended in the middle allowing maximum flexibility on contoured ground. This feature also assures even weight distribution.
