Question 4 NECO • 2023 • AGRICULTURAL_SCIENCE • practical

A small tractor equipped with a single‑point plough is to be used on a field. The plough requires a draft force of 1 500 N when the tractor moves at a speed of 5 km h⁻¹. The tractor’s engine is rated at 25 kW at 2 000 r.p.m. The width of the plough is 1.2 m and a field efficiency of 80 % is expected. Fuel consumption of the tractor at full load is 5 L h⁻¹.

Question Parts

( a )

Calculate the power required to pull the plough at the given speed.

( b )

Compare the required power with the tractor’s rated power and state whether the tractor is adequately powered.

( c )

Assuming fuel consumption varies proportionally with engine load, estimate the fuel used when the tractor operates for 8 hours at the calculated load.

( d )

Calculate the theoretical field capacity (ha h⁻¹) of the plough under the given conditions.
