Level the playing field? (3)
I believe the answer is:
mow
'level the playing field?' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for mow that I've seen before include "'Cut down, hay, say (3)'" , "Cut (e.g. grass)" , "Cut grass or grain" , "'Cut, grass say (3)'" , "Cut down, usually grass" .)
