Neco 2025 Agricultural Science Question 14
Practice objective / multiple choice question 14 from the 2025 Neco Agricultural Science examination.
A tractor must pull a moldboard plough. The draft force required is given by \(D (\text{kN}) = 0.5 + 0.02 v^{2}\), where \(v\) is the tractor speed in km/h. The tractor travels at 5 km/h. Its rolling resistance equals 0.03 times its weight. The tractor weight is 3,000 kg and the transmission efficiency is 85 %. Determine the minimum engine power required (in kW).
