Claim 10:
11. A working machine, comprising:
a prime mover;
a traveling pump configured to be driven by the prime mover to output operation fluid;
a traveling motor configured to be driven by the operation fluid outputted by the traveling pump and to switch a motor speed between a first speed and a second speed higher than the first speed;
a traveling switching valve configured to be switched between a first state allowing the traveling motor to rotate at the first speed and a second state allowing the traveling motor to rotate at the second speed;
a switch configured to output a speed-shifting signal representing either an accelerating process to switch the traveling switching valve from the first state to the second state or a decelerating process to switch the traveling switching valve from the second state to the first state; and
a controller configured or programmed to switch the traveling switching valve and to set a switching time required for switching the traveling switching valve after obtaining the speed-shifting signal from the switch, the switching time being different depending on whether to perform the accelerating process or the decelerating process.
