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

'what's this about grass-cutting' is the definition.
The definition suggests a singular noun which matches the answer.

'what's this about' is the wordplay.
'this about' indicates an anagram.
'whats' anagrammed gives 'SWATH'.

Can you help me to learn more?

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