Practice objective / multiple choice question 45 from the 2025 Neco Agricultural Science examination.
A combine harvester requires a power of 150 kW on level ground to overcome soil resistance (drawbar pull 12 kN). The field has a uniform slope of 5\% and the required power increases by 10\% for each percent of slope due to extra traction demand. The drivetrain efficiency is 85\%. What is the minimum engine power rating (in kW) that the harvester must have to operate safely on this slope?
