As a dope peddler, he needs no tractor (6)
I believe the answer is:
pusher
'tractor' is the definition.
(thesaurus)
'as a dope peddler he needs no' is the wordplay.
I cannot quite understand how this works, but
'he' is within the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for pusher that I've seen before include "A seller of drugs on the streets" , "Street seller of illegal drugs" , "Criminal who sells illegal drugs" , "See 20" .)
