A working machine includes a machine body, a traveling device, a traveling motor configured to provide power to the traveling device and to be switched between a first speed and a second speed higher than the first speed, a traveling operation member, an operation detector to detect an operation extent of the traveling operation member, a traveling pump driven in response to the operation extent, a revolution detector to detect a motor revolving speed of the traveling motor, and a controller configured, with the traveling operation member maintained at a predetermined operation extent, to switch the traveling motor from the second speed to the first speed when the motor revolving speed is equal to or less than a deceleration threshold which is less than a first top or maximum revolving speed of the traveling motor switched to the first speed, for the predetermined operation extent.
