ABSTRACT:
A collapsible tool bar is provided for carrying agricultural earth-working tools and includes a normally horizontal main tool bar section and at least one outer wing section. The main and wing section are connected by a hinge which has a main hinge plate secured to one of the tool bar sections and a wing hinge plate secured to the other tool bar section. The hinge also includes an intermediate hinge plate connecting the main and wing hinge plates. The main hinge plate is rotatably attached to said intermediate hinge plate about a substantially vertical axis. Means are provided for selectively securing the main hinge plate to the intermediate hinge plate. The wing hinge plate is rotatably attached to the intermediate hinge plate about a substantially horizontal axis. Means are provided for urging said outer wing section in a downward direction when the main hinge plate is secured to the intermediate hinge plate.
