A tractor is pulling a drawbar tillage implement at a groundspeed of 1.6 m/s. The total rear axle static load is 35 kN, thewheelslip is 0.1, and the value of mobility number for theparticular tyre and soil is 2.84. The driving tyre radius is 0.6 m,and the engine speed is 2100 rpm, and the overall gear transmissionmechanical efficiency is 79%.
