A work vehicle is capable of readily knowing an amount of soil built up on a front surface of a blade. A motor grader includes a vehicular body frame, a blade, and an image pick-up apparatus. The blade is arranged between a front end of the vehicular body frame and a rear end of the vehicular body frame. The blade is supported on the vehicular body frame. The image pick-up apparatus is arranged in front of the blade. At least a part of the blade is included within an angle of view of the image pick-up apparatus. A revolving operation of the blade is automatically controlled based on the amount of soil built up on the front surface of the blade.
