A tractor PTO operated rotary disc mower has 4 rotating discs and the width of cut of each disc is 60 cm without any overlap. The specific power losses to air, stubble and gear-train friction is 2.5 kW per meter of cutting width. The specific cutting energy requirement is 2.0 kJ m−2. If the machine is operated at a forward speed of 6 km h−1, the PTO power requirement in kW (round off to 2 decimal places) is _______.
