PURPOSE: A device for rotating a cooling fan of a combine-harvester engine is provided to prevent the deterioration of cooling and generating performance even when rotation direction of a cooling fan is converted, thereby keeping smooth operation states. CONSTITUTION: A device for rotating a cooling fan of a reaper engine includes a guide roller(R) mounted on a lower part than a lower supporting point(P) of the generator. The guide roller properly presses a main belt(14) by a proper tension while rotation direction of a cooling fan is changed, so that the deviation of the belt is prevented and the cooling and generation performance of an engine is kept stably. |
