ABSTRACT:
A device for controlling the height of a blade of a tracked vehicle includes a blade height position detector, a blade height controller for raising and lowering the blade, and a device for setting an initial height of the blade. When the transmission of the vehicle is shifted from the reverse to the forward position, the height of the blade is lowered to the target value. A switch selects between the target value set by the initial height setting device and a manually selected height depending whether or not the switching device selects the automatic operation or manual operation of the blade height controller.
