Claim 2:
3. The working machine according to claim 1, wherein
the controller is configured or programmed
to set a plurality of rotation speeds of the prime mover between the threshold rotation speed and the target prime mover rotation speed defined as actual restoration-controlled prime mover rotation speeds,
to perform the restoration control to increase the target fan rotation speed in a stepwise manner starting from a minimum rotation speed which is the smallest one of the actual restoration-controlled prime mover rotation speeds, and
to define a difference between a maximum rotation speed which is the maximum one of the set actual restoration-controlled prime mover rotation speeds and the threshold rotation speed as a fixed value, and change a difference between the maximum rotation speed and the target prime mover rotation speed in correspondence to variation of the instructed prime mover rotation speed.
