Abstract:
To provide a motor grader capable of improving work efficiency.SOLUTION: A motor grader M includes: a vehicle body 1; slip detection means 3 for detecting slip of the vehicle body 1; an earth removing blade 25 for cutting a ground G; a lifting cylinder 23 and a tilt cylinder 24 for adjusting a relative position of the earth removing blade 25 in the vehicle body 1 and actuating by a hydraulic pressure; hydraulic pressure detection means 5 for detecting a hydraulic pressure; a computerization automatic control device 6 for performing computerized automatic control of the height of the earth removing blade 25; and a slip control device 7 for determining whether or not the vehicle body 1 is slipping based on the detection information by the slip detection means 3 and for determining whether or not the hydraulic pressure is larger than a predetermined threshold value based on the detection information by the hydraulic pressure detection means 5. In the case where the slip is detected or the case where the detected hydraulic pressure is larger than the threshold value, the slip control device 7 cuts off the computerized automatic control and resets the threshold value.SELECTED DRAWING: Figure 2
