Question

(3) A 2-wheel drive tractor with a total weight of 23 kN has a wheel base of 2100 mm and the centre of gravity is 710 mm ahead of rear axle centre line. The tractor has a constant drawbar pull of 15 kN on a concrete surface at a forward speed of 6 km/h with a drawbar height of 485 mm. The axle power is 33.3 kW. Determine the weight transfer onto the rear axle due to the drawbar pull, .the coefficient of traction, and . the tractive efficiency, the weight transfer onto the rear axle as calculated by the approximate Dynamic Weight transfer equation (R Ro C Fdb) (30 marks)
