Abstract
1,223,865. Motor graders. CATERPILLAR TRACTOR CO. 4 March, 1968 [22 May, 1967], No. 10338/68. Heading E1F. The power supply to the means for moving the grader blade assembly 13 of a motor grader relative to the frame 12 of the grader is controlled by a system which is designed to interrupt the supply of power to the means when the assembly is nearing contact with a frame-mounted, side shifting racking or with the frame. The system is such as to permit of manual overriding when required of the power shut off initiating means, e.g. pressureactuated contact switches 27, 29 of the control system. Two control circuits are described.
