Weed whacker (3)
I believe the answer is:
hoe
'weed whacker' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for hoe that I've seen before include "Plymouth - -" , "Weed" , "Gardening tool" , "Weeding tool" , "Tool for loosening soil and scraping up weeds" .)
