Harrow playboy? (4)
I believe the answer is:
rake
I believe this clue is a double definition.
'harrow' is the first definition.
(thesaurus)
'playboy?' is the second definition.
(old-fashioned term for a womanising man)
(Other definitions for rake that I've seen before include "disreputable fellow" , "Mast or funnel inclination" , "Leaves collector" , "Garden tool; slope angle" , "His Progress, Hogarth" .)
