Abstract
An earthmoving machine includes a work implement, a distance calculation unit, and a hydraulic cylinder control unit. The work implement includes a boom, an arm, and a bucket. The distance calculation unit calculates a distance between a monitoring point in the bucket and design topography representing an aimed shape of a land grading target. The hydraulic cylinder control unit outputs a command signal for lowering the boom when the distance between the monitoring point and the design topography is equal to or smaller than a prescribed value and when the bucket is expected to move in such a direction that the monitoring point moves away from the design topography as a result of an operation of the arm.
