Abstract
A working machine includes a prime mover, a traveling device, a traveling motor, a traveling pump, a circulation fluid passage, a traveling switching valve shiftable between a first state corresponding to a first speed of a hydraulic motor and a second state corresponding to a second speed of the hydraulic motor, a brake, an actuation valve configured to output the hydraulic pressure applied to the traveling pump, and change the hydraulic pressure output therefrom, and a controller configured or programmed to control the traveling switching valve, the brake and the actuation valve, and being capable of activating a first mode. The controller is configured or programmed to, when activating the first mode, shift the brake into a braking state, shift the traveling switching valve into the second state, and control the actuation valve so as to set the hydraulic pressure output from the actuation valve to a predetermined pressure.
