Gce Model Questions Vol1 2019 Agricultural Science Question 8
Practice objective / multiple choice question 8 from the 2019 Gce Model Questions Vol1 Agricultural Science examination.
A tractor's engine runs at 1500\,rpm. The gearbox reduces the speed by a ratio of 4\,:\,1 and the final‑drive reduces it further by 3\,:\,1 before it reaches the wheels, which have a radius of 0.5\,m. The tractor pulls a plough 1.5\,m wide, but because of overlap only 90\% of the plough width is effective. Using the field‑capacity formula \(\text{Capacity (ha\,h}^{-1}\text{)} = \dfrac{\text{speed (km\,h}^{-1}\text{)} \times \text{effective width (m)}}{10}\), calculate the theoretical field capacity in hectares per hour, rounded to two decimal places.
