With it farmers make good turnover? (6)
I believe the answer is:
plough
'turnover?' is the definition.
Although both the answer and definition are singular nouns, I cannot see how one could define the other.
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for plough that I've seen before include "Farm tool and group of stars" , "Seven stars on the farm?" , "Make furrows" , "Furrow cutter" , "Soil churner" .)
