Abstract
To provide a work machine in which traveling devices and an implement device can be operated by common operating levers, wherein switching operation is easy and a changeover is easily confirmed. Inside a cab of the work machine, there are provided travel pedals, with which the traveling devices can be operated, and operating levers, with which the traveling devices and the implement device can be operated. A changeover switch is provided on a console positioned in the vicinity of one side of an operating sheet. The changeover switch switches over between a traveling mode, in which traveling operation is possible by the operating levers, and a work mode, in which implement operation is possible by the operating levers. The work machine has a controller which makes it possible to work by the operating levers when the travel pedal is not stepped on in the case where the work mode or traveling mode is selected by the changeover switch, and makes it possible to travel by the operating levers only when the travel pedal is stepped on in the case where the traveling mode is selected by the changeover switch.
