<p>The work machine is provided with a driving device for driving a radiator cooling fan using the motive power of the engine. The driving device is provided with a two-system motive power-transmitting mechanism comprising a forward rotation system motive power-transmitting mechanism, which is capable of transmitting a forward rotation power with an endless rotation belt, and a reverse rotation system motive power-transmitting mechanism, which is capable of transmitting a reverse rotation power with another endless rotation belt. A forward-reverse rotation selection mechanism (6), which is capable of alternately selecting the motive power from one or the other of the motive power-transmitting mechanisms and transmitting same to the input rotator (72) of the radiator-cooling fan, is also provided.</p> |
