Abstract
A working machine includes first and second traveling pumps, an acquirer to acquire the number of revolutions and the rotation direction of each of first and second traveling motors, a determiner to, based on the acquired number of revolutions and the acquired rotation direction, determine whether a machine body is in a straight traveling state or a turn traveling state, and a controller configured or programmed to, when switching from a first state allowing rotation speeds of the first and second traveling motors to increase up to a first maximum speed, to a second state allowing the rotation speeds to increase up to a second maximum speed higher than the first maximum speed, or vice versa, is performed, reduce an amount of hydraulic fluid supply from the pumps to the motors according to the straight traveling state or the turn traveling state of the machine body.
