  • Publication number: 20230287654
    Abstract: A working machine includes a traveling pump to be operated by power of a prime mover and deliver a hydraulic fluid; a traveling motor that rotates using the delivered hydraulic fluid; an operation valve that changes pilot pressure of a pilot fluid outputted to the traveling pump in response to operation of an operation member; an actuation valve that operates based on a control signal and changes primary pressure that is the pilot pressure of the pilot fluid supplied to the operation valve; a controller that controls opening of the actuation valve by outputting the control signal to the actuation valve; and a first detector that detects an actual number of revolutions of the traveling motor. The controller includes a changer that changes setting of the control signal such that the opening of the actuation valve increases as the actual number of revolutions of the traveling motor decreases.
