Abstract: A tool for temporarily supporting a cutting blade in its correct angular orientation to facilitate its installation on a grader. The tool comprises an elongate bar, and first and second brackets mounted on the bar at spaced locations. Each bracket includes a slot for receiving and supporting the cutting blade. The tool further comprises a suspension member on the bar, intermediate the brackets. The suspension member is at such an orientation with respect to the brackets that when the tool is suspended by the suspension member, a blade supported in the brackets is at approximately the angle at which it is mounted on the grader.
