FIELD: machine engineering.
SUBSTANCE: implementation of the method includes a first power generation device, a second power generation device, a first cooling fan hydraulically connected to the first power generation device, a second cooling fan hydraulically connected to the second power generation device, a controller and fan control device installed and connected by means of fluid between the first cooling fan and the second cooling fan. It is determined whether the first power generation device or the second power generation device is operating at the drive shaft speed below the threshold speed value. It is detected whether the diagnostic fault code is active with respect to the fan control device. The signal is sent to the fan control device. The fan control device is activated. Hydraulic power to the first cooling fan and the second cooling fan is provided depending on, whether the first power generation device or the second power generation device operates at the speed of the drive shaft above the threshold speed value. Working machines are also proposed.
EFFECT: working machine cooling system is controlled.
