Abstract
A seeding machine having a wing frame with planting units. The planting units are coupled to the wing frame by a pivot arm. The pivot arms move the planting units between a horizontal working configuration and a vertical transport configuration. An operator walkway is located above the planting units. The operator walkway comprises a walkway frame and a footboard. The walkway frame is pivotally coupled to the wing frame segment by a walkway frame pin. The footboard is pivotally coupled to the walkway frame by a footboard pin. As the planting units are moved from their horizontal working configuration to their vertical transport configuration the walkway frame and attached footboard are automatically folded between the planting units and the respective wing frame segment.
