Practice objective / multiple choice question 42 from the 2017 Neco Model Questions Vol1 Agricultural Science examination.
The diagram shows a tractor with a PTO delivering \(45\) kW at \(540\) rpm, driving a rotary tiller through a gear set with ratio 1:2. The tiller requires \(30\) kW at a working depth of \(10\) cm when used on the same soil as a conventional disc plough, and its power requirement increases linearly with depth. Using the information in the diagram, determine the greatest tillage depth (in cm) that can be attained without exceeding the tractor's PTO power.
