Claim 18:
19. The working machine according to claim 18, wherein
the controller is configured or programmed to selectively perform either automatic deceleration to automatically reduce the rotation speed of the traveling motor when a predetermined deceleration condition is satisfied or manual deceleration to reduce the rotation speed of the traveling motor according to the speed-shift command issued by the speed-shift switch,
the controller, when performing each of the automatic deceleration and the manual deceleration, is configured or programmed to change a control value of a second control signal input to a proportional solenoid valve serving as the traveling change-over valve so as to shift the traveling change-over valve into a state to reduce the rotation speed of the traveling motor,
a second change rate of changing a control value of the second control signal and a shifting period included in the delay time are each defined as the control parameter, the shifting period extending from start of changing the control value of the second control signal until the operation state of the traveling change-over valve is completely shifted, and
the controller, when each of the automatic deceleration and the manual deceleration, is configured or programmed to change a value of the second change rate and a length of the shifting period, which are each defined as the value of the control parameter.
