What's possibly cut by the scythe (5)

I believe the answer is:

swath

I'm a little stuck... Click here to teach me more about this clue!

'cut by the scythe' is the definition.
I can't judge whether this definition defines the answer.

'what's possibly' is the wordplay.
'possibly' is an anagram indicator.
'whats' anagrammed gives 'SWATH'.

Can you help me to learn more?

(Another definition for swath that I've seen is " cut in field".)

I've seen this clue in The Globe and Mail.
