摘要： A work machine includes: a satellite communication antenna for detecting a position of an upper swing structure; angle sensors detecting postures of two work devices; position computing devices that calculate postures/positions of the two work devices on the basis of outputs from the satellite communication antenna and the angle sensors; a display device on which the position of at least one work device of the two work devices and a position of a target surface are displayed; a display selection switch that outputs a first input signal for displaying a work device selected by an operator from between the two work devices on the display device; and a display changeover section that displays the work device corresponding to the first input signal input from the display selection switch out of the two work devices and the position of the target work object of the work device on the display device.
