Abstract
A work machine is provided that can achieve an automatic brake retention function without hindering work. The work machine includes a vehicular body that travels, a work implement supported on the vehicular body, an accelerator operation device operated to increase a traveling speed of the vehicular body, a brake operation device operated to decrease the traveling speed of the vehicular body, and a controller. The controller performs automatic brake retention control to retain a braking force to maintain a travel-stopped state of the vehicular body when the traveling speed of the vehicular body becomes less than or equal to a threshold by operation of the brake operation device, and release the retention of the braking force by operation of the accelerator operation device. The controller determines whether work is being performed by the work implement, and when work is being performed, disables the automatic brake retention control.
