A two-wheel drive tractor with rear wheel rolling radius of $600 \mathrm{~mm}$ develops a tractive force of $18.5 \mathrm{kN}$ at a wheel slip of $12 \%$. The engine speed is $2400 \mathrm{rpm}$ and the transmission ratio from the engine to the rear wheels is 120: 1 . If the tractor experiences a motion resistance of $1.75 \mathrm{kN},$ the drawbar power developed by the tractor will be____________ $\mathrm{kW}$.
