Folding walkway for seeding machine
First Claim
1. An agricultural implement comprising:
- a frame;
a pivot arm having a first end and a second end, the first end of the pivot arm is pivotally mounted to the frame, the pivot arm having a working position and a transport position;
a ground engaging tool is mounted to the second end of the pivot arm, when the pivot arm is in its working position the ground engaging tool is in contact with the ground;
an operator walkway pivotally mounted to the frame, the operator walkway having a horizontal working position and a stored transport position that is predominantly vertical, whereby the operator walkway is automatically pivoted from its horizontal working position to its stored transport position as the pivot arm is pivoted from its working position to its transport position.

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.
