Producer of harvest in the fall (7)
I believe the answer is:
cropper
'the fall' is the definition.
(I have seen 'Heavy fall' mean 'cropper' so perhaps 'fall' could also mean 'cropper')
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for cropper that I've seen before include "Come a --, suffer disaster" , "Heavy fall" , "failure" , "Disastrous mistake or fall" .)
