A control method of a working machine is a control method of a working machine capable of replacing an attachment of a working unit. This control method includes displaying, on a display device, attachment information related to the attachment being mounted at the time of startup of the working machine by a startup manipulation. ## Claims ### Claim 1 A control method of a working machine capable of replacing an attachment of a working unit, the control method comprising displaying, on a display device, attachment information related to the attachment being mounted at a time of startup of the working machine by a startup manipulation. ### Claim 2 (depends on 1) The control method of the working machine according to claim 1, further comprising adjusting, based on the attachment information, an interference avoidance function of controlling an operation of the working unit so as to avoid interference of the working unit with a driving unit. ### Claim 3 (depends on 1) The control method of the working machine according to claim 1, wherein the working machine can operate even while the attachment information is displayed. ### Claim 4 (depends on 1) The control method of the working machine according to claim 1, further comprising displaying, on the display device, a home screen after displaying the attachment information. ### Claim 5 (depends on 1) The control method of the working machine according to claim 1, further comprising reading the attachment information into the display device at the time of startup of the working machine. ### Claim 6 (depends on 5) The control method of the working machine according to claim 5, further comprising performing informing when the reading of the attachment information fails. ### Claim 7 (depends on 1) The control method of the working machine according to claim 1, wherein the attachment information is displayed after displaying a start screen that is first displayed on the display device after the startup of the working machine. ### Claim 8 (depends on 7) The control method of the working machine according to claim 7, wherein the attachment information is displayed after specific information is displayed after displaying the start screen. ### Claim 9 (depends on 8) The control method of the working machine according to claim 8, further comprising changing a manipulation pattern, which is a correspondence relationship between a manipulation of a manipulation device and an operation of the working machine, wherein the specific information is information related to a current manipulation pattern. ### Claim 10 (depends on 1) The control method of the working machine according to claim 1, further comprising: executing automatic disabling processing of automatically disabling a specific function related to the working machine when a cancellation condition including that a stop manipulation of the working machine is performed in a state where the specific function is enabled is satisfied; and displaying, on the display device, disabling confirmation information indicating that the specific function is disabled after the startup of the working machine by the startup manipulation after executing the automatic disabling processing. ### Claim 11 (depends on 10) The control method of the working machine according to claim 10, wherein the cancellation condition includes a condition other than the stop manipulation of the working machine. ### Claim 12 (depends on 10) The control method of the working machine according to claim 10, wherein the disabling confirmation information is displayed only at a time of first startup of the working machine after executing the automatic disabling processing. ### Claim 13 (depends on 10) The control method of the working machine according to claim 10, wherein the disabling confirmation information is displayed next to the attachment information. ### Claim 14 (depends on 1) The control method of the working machine according to claim 1, wherein the attachment information is displayed on the display device together with operating information related to an operating state of the working machine. ### Claim 15 (depends on 1) A working machine control program for causing one or more processors to execute the control method of the working machine according to claim 1. ### Claim 16 A working machine control system used for a working machine capable of replacing an attachment of a working unit, the working machine control system comprising a display processing unit that displays, on a display device, attachment information related to the attachment being mounted at a time of startup of the working machine by a startup manipulation. ### Claim 17 (depends on 16) A working machine comprising: the working machine control system according to claim 16; and a machine body.
