The speed reductions in the $1^{\text {st }}$ low gear of a tractor gearbox and differential with final drive are 5: 1 and 40: 1 , respectively. For the tractor developing $24 \mathrm{~kW}$ power at an engine rpm of 2000 with an overall power transmission efficiency of $80 \%$, the total torque in $\mathrm{kN} \mathrm{m}$ available at the wheel axle will be
