A working machine includes a hydraulic pump and a travel control valve for each of left and right traveling unit. A tank-side fluid channel of the travel control valve includes an actuator control valve for controlling another actuator. When both travel control valves are operated at the same time and when at least one actuator control valve is operated, a merge control valve is opened to merge hydraulic fluid ejected from the two hydraulic pumps. At the same time, a feed switching valve is opened so that a different hydraulic pump supplies hydraulic fluid to the actuator control valve.
