WORKING MACHINE

A working machine includes a machine body; a prime mover mounted on the machine body; a cooling fan to generate cooling air for cooling the prime mover; a cooler having a ventilation surface portion on which the cooling air hits, to cool a coolant to be circulated and supplied to the prime mover; and a controller. The cooler and the controller are disposed upstream of the prime mover in a flow direction of the cooling air. The controller is disposed at a position not overlapping the ventilation surface portion when viewed in the flow direction of the cooling air.
