Abstract
A shovel includes an arm rotatably attached to a boom rotatably attached to a revolving body; a bucket rotatably attached to the arm; a tilt mechanism configured to support the bucket that can be tilted to the arm; a bucket tilt angle sensor configured to detect a tilt angle of the bucket; and a tilt angle controller configured to control adjusting the tilt angle, wherein the tilt angle controller adjusts the tilt angle by automatic control so that a bucket line of the bucket becomes parallel to a target excavation surface.
