ABSTRACT:
A stacking tool bar including a wing flex structure is disclosed which includes a main tool bar section having right and left wing sections positioned at the outer ends thereof. Hydraulically operated lift arms are operatively connected to the wing sections for pivotally moving the wing sections from a field working position to a transport position. Double-acting flex cylinders are provided for dampening the upward and downward movement of the outer ends of the wing sections as the tool bar is pulled through the field. The double-acting flex cylinders also enable the wing sections to be disposed in a horizontally disposed condition when the wing sections have been pivotally moved upwardly to their folded and stacked position.
