Abstract:
1. An agricultural implement, comprising: a tool bar assembly comprising a central tool bar, a first wing tool bar rotatably coupled to a first end of the central tool bar via a first hinge, a second wing tool bar rotatably coupled to the first wing tool bar via a second hinge, a third wing tool bar rotatably coupled to a second end of the central tool bar via a third hinge, and a fourth wing tool bar rotatably coupled to the third wing tool bar via a fourth hinge, wherein the first and third hinges each comprise at least one pin to facilitate transition of the agricultural implement between a working position and a transport position, and each pin that facilitates rotational movement of the first wing tool bar relative to the central tool bar and each pin that facilitates rotational movement of the third wing tool bar relative to the central tool bar is non-parallel to a direction of travel of the agricultural implement; wherein to transition the agricultural implement from the working position to the transport position, the second wing tool bar folds over and substantially parallel to the first wing tool bar while the first wing tool bar is in the working position, the fourth wing tool bar folds over and substantially parallel to the third wing tool bar while the third wing tool bar is in the working position, and the first and third wing tool bars fold via the first and third hinges, respectively, crosswise over the central tool bar such that the first and second wing tool bars each cross the third and fourth wing tool bars.
