Abstract:
When a blade load is reduced from a value greater than or equal to a first set load value to a value less than the first set load value, a blade control device is configured to set a virtual designed surface to be closer to a blade than a designed surface is, and is configured to allow the blade to pivot above the virtual designed surface.
