Do some yard work (3)
I believe the answer is:
mow
'do some yard work' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for mow that I've seen before include "'Cut down, hay, say (3)'" , "Cut (e.g. grass)" , "Cut down, usually grass" , "'Cut, grass say (3)'" , "Scythe" .)
