Criminal on parole perhaps, cut grass (6)
I believe the answer is:
outlaw
'criminal' is the definition.
('outlaw' can be a synonym of 'criminal')
'on parole perhaps cut grass' is the wordplay.
'on parole perhaps' becomes 'out' (someone on parole is out of prison).
'cut' means to remove the last letter.
'grass' becomes 'lawn' (I've seen this before).
'lawn' with its final letter taken away is 'law'.
'out'+'law'='OUTLAW'
(Other definitions for outlaw that I've seen before include "Ban - bandit" , "eg Robin Hood" , "He broke the rules in the old West" , "Ban; fugitive" , "Robin Hood, for one" .)
