Gce Model Questions Vol1 2023 Agricultural Science Question 11
Practice objective / multiple choice question 11 from the 2023 Gce Model Questions Vol1 Agricultural Science examination.
A three‑mouldboard plough has a total effective width of 0.9 m. When the plough depth is set to 0.15 m, a spring‑scale attached to the drawbar reads 1200 N. Assume that draft force varies directly with both plough depth and total width. The tractor moves at 5 km h^{-1} and the power transmission efficiency from the engine to the drawbar is 80 %. What minimum engine power, in kilowatts (kW), is required to operate the plough at a depth of 0.25 m?
