To provide a work machine which can surely blow out dust over a long time by a fan.SOLUTION: A work machine comprises: a machine body; an engine which is mounted on the machine body; a radiator which cools cooling water supplied to the engine; a first fan which is arranged on one surface side of the radiator and is rotatable in a first direction where the air stream for taking the outside air into the inside of the machine body is generated and in a second direction in which the air stream for discharging the air in the machine body to the outside is generated; and a control device which controls the driving of the first fan. The control device drives the first fan so as to repeat an operation process including a speed increasing operation for increasing the rotation speed in the second direction and a speed decreasing operation for decreasing the rotation speed in the second direction increased by the speed increasing operation in a prescribed period.SELECTED DRAWING: Figure 10 【課題】ファンにより長時間にわたって確実にダストを吹き飛ばすことができる作業機を提供すること。【解決手段】作業機は、機体と、前記機体に搭載されたエンジンと、前記エンジンに供給される冷却水を冷却するラジエータと、前記ラジエータの一方面側に配置され、前記機体内部に外気を取り入れる気流を発生させる第１方向と、前記機体内部の空気を外部に排出する気流を発生させる第２方向とに回転可能な第１ファンと、前記第１ファンの駆動を制御する制御装置と、を備え、前記制御装置は、前記第２方向の回転数を増加させる増速動作と、前記増速動作により増加した前記第２方向の回転数を低下させる減速動作と、を含む動作プロセスを、所定期間内に繰り返すように前記第１ファンを駆動させる。【選択図】図１０
