Harvesting tool (6)
I believe the answer is:
scythe
'harvesting tool' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for scythe that I've seen before include "It's useful for hacking" , "Old mowing implement for hand use" , "Reaper's tool" , "Long-handled tool for cutting grass or grain" , "Large sickle" .)
