Abstract
A hydraulic excavator loads a load onto a loaded machine. The hydraulic excavator includes a work implement and a controller. The work implement includes a bucket. The controller senses an amount of natural lowering of the bucket in a stand-by state in which the hydraulic excavator waits for entry of the loaded machine and controls the work implement to raise the bucket based on the amount of natural lowering.
