A small farm uses a compact tractor to pull a single‑bottom disc plough across a field. The illustration shows the tractor, the power‑take‑off (PTO) shaft, the disc plough, and the field dimensions. The tractor travels at a constant speed of 5 km h, the effective working width of the disc plough is 1.5 m, and a field efficiency of 80 % is assumed for turning and overlap.

Question Parts

( a )
Identify the three main components of the power transmission system between the tractor and the plough as shown in the illustration.
( b )
Explain how the tractor’s engine power is transferred to the rotating disc of the plough and why maintaining the correct PTO speed is important.
( c )
Calculate the theoretical field capacity of the tractor‑plough combination in hectares per hour (ha h⁻¹). Show the formula used and each step of the calculation.
( d )
Discuss two advantages of using a tractor‑driven disc plough over manual tillage for a small farm.
