It can pull out old agricultural machinery (9)
I believe the answer is:
extractor
'it can pull' is the definition.
The definition suggests a singular noun which matches the answer.
'old agricultural machinery' is the wordplay.
'old' becomes 'ex' (prefix meaning former or onetime).
'agricultural machinery' becomes 'tractor'.
'ex'+'tractor'='EXTRACTOR'
'out' is the link.
Can you help me to learn more?
(Other definitions for extractor that I've seen before include "Juice-maker" , "dentist" , "Sort of fan" , "Remover" , "Kind of fan that sucks out stale air" .)
