Gardening aid welcomed by more women on retirement (5)
I believe the answer is:
mower
'gardening aid' is the definition.
(machine used for gardening)
'welcomed by more women on retirement' is the wordplay.
'welcomed by' says the answer is hidden in the clue.
'on retirement' shows that the letters should be reversed in order (retire can mean to go back).
'rewom' is hidden in the letters of 'more women'.
'rewom' written backwards gives 'MOWER'.
(Other definitions for mower that I've seen before include "Grass cutter" , "Machine for cutting grass" , "Tool for cutting grass" , "Patrick _; Rodney Blackstock in Emmerdale" , "Gardening machine" .)
