Abstract
There is provided a work vehicle in which a work implement can be freely operated. The work vehicle includes: a design surface information acquiring unit for acquiring data of a design surface indicative of a target shape of a work object by the work implement; a cutting edge position computing unit for computing a position of a cutting edge of a bucket; and an operation restricting unit for executing operation restriction control by which, when the cutting edge of the bucket comes closer to the design surface, operation of the work implement is stopped before the cutting edge of the bucket reaches the design surface. In a case where the cutting edge is located away from the design surface in a downward perpendicular direction by a prescribed distance or longer, the operation restricting unit does not execute the operation restriction control.
