ABSTRACT:
A floating wing apparatus for toolbars which allows each wing to ride smoothly over terraced or rolling terrain, thereby providing a continuous, even contact between the implements carried thereon and the ground. Upper and lower pivot arms extend from the central section of the toolbar to the inner end of each wing section to form a parallelogram linkage which maintains the wing sections in a substantially horizontal orientation at all times, whether in the raised or lowered position. The upper pivot arm is pivotally connected to a pivot post, which is in turn pivotally connected to the central section. When working the land, this pivot post allows the wing sections and their attached implements to float or ride over uneven, rolling terrain. When the implements must be raised above the ground as during turning at the end of a field or when the wings are raised to the retracted position, the pivot posts are locked to a vertical position by means of hydraulic cylinders.
