A small tractor is to be used for ploughing a 2‑hectare field. The tractor has a rated engine power of 15 kW and consumes fuel at a rate of 5 L per hour when operating at full load. The plough attached to the tractor has a working width of 0.75 m and the desired forward speed is 5 km/h.

Question Parts

( a )
Calculate the total time required to plough the entire field, assuming continuous operation and no overlap between passes.
( b )
Based on the time calculated in part (a), determine the total volume of fuel required for the operation.
( c )
The draft force (D) required to pull the plough can be estimated by D = 1000 × w × v², where w is the plough width in metres and v is the tractor speed in m/s. Compute the draft force, the power needed to overcome this draft (P = D × v), and state whether the tractor’s rated power of 15 kW is adequate.
( d )
List two precautionary measures that should be observed when operating the tractor on wet soil to avoid slippage and soil compaction.
