Cut taken by a mower when he’s on strike (6)
I believe the answer is:
swathe
'cut' is the definition.
(I have seen 'considerable cut' mean 'swathe' so perhaps 'cut' could also mean 'swathe')
'he's on strike' is the wordplay.
'on' means one lot of letters go next to another.
'strike' becomes 'swat' (**).
'he' after 'swat' is 'SWATHE'.
'taken by a mower when' acts as a link.
This may not be correct. Some or all of it may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for swathe that I've seen before include "Wrap in layers of, say, bandages" , "row after reaping" , "Broad strip or area; wrap in fabric" , "considerable cut" , "A broad strip as of cut grass" .)
