Abstract (en)
Provided is a work machine (1) capable of continuing work by automatic operation over a large area. The work machine (1) includes a controller that makes an upper turning body (22) and a work device (30) perform a series of motions including processing motion a plurality of times. The controller performs: shifting the start position of the processing motion in the next series of motions in the turning direction of the upper turning body (22) when a processing work performed by a series of motions reaches a predetermined stage; making a lower traveling body (21) perform an area change movement when the processing work reaches a predetermined stage while the start position has reached a change limit plane (75); and setting an after-movement start position so as to make the processing work after the area change movement continued with the processing work before the area change movement.
