One takes out old farm vehicle (9)
I believe the answer is:
extractor
'one takes out' is the definition.
(someone who extracts)
'old farm vehicle' is the wordplay.
'old' becomes 'ex' (prefix meaning former or onetime).
'farm vehicle' becomes 'tractor' (I've seen this before).
'ex'+'tractor'='EXTRACTOR'
(Other definitions for extractor that I've seen before include "Eg, kitchen fan" , "Juice-maker" , "Kind of fan that sucks out stale air" , "Variety of fan" , "Device for removing air from a space" .)
