Abstract
A device for improving the workability and drivability of a tracked vehicle whose blade height is automatically controlled, in which when changeover of a speed step from reverse to forward is detected by a transmission lever position detector (3), a controller (15) controls to raise or lower the blade (8) to a target value which is the height of the blade (8) initially set by an initial height setter (4). With a blade raising lever (1) operated, the blade (8) is controlled to rise or lower in proportion to the height of the blade during manual operation. The height is detected by a blade-height detector (14) and the blade is controlled to rise or lower to a target value which is the detected value of height.
