Question 4 NECO • 2024 • AGRICULTURAL_SCIENCE • essay

A farmer plans to use a tractor‑drawn moldboard plough to prepare a field. The plough has a total width of 1.2 m. The soil resistance to ploughing is estimated at 15 kN per metre of plough width. The tractor can maintain a forward speed of 5 km/h while pulling the plough. The tractor's power take‑off (PTO) efficiency is 85 %. Fuel consumption of the tractor at full load is 0.25 L per kilowatt‑hour. Using this information, answer the following:

( a )

Calculate the total draw‑bar pull (in kilonewtons) required to pull the plough through the soil.

( b )

Determine the minimum engine power (in kilowatts) that the tractor must develop to sustain the required draw‑bar pull at the given speed.
