CONNECTING THE HYDRAULIC MOTOR OF THE FAN
6.5.1
Description of the function
The hydraulic fan is powered directly from the tractor´s hydraulic system.
For proper operation, the hydraulic pump of the tractor must supply sufficient amount of oil so that the
fan revolutions are not affected by decreased number of revolutions of the tractor engine or by another hydraulic
circle being switched on.
The fan revolutions are set by regulating the oil flow rate. To change the fan revolutions, the tractor must
be equipped with regulation of the oil flow rate.
