Fan found in abandoned farm vehicle (9)

Ross

I believe the answer is:

extractor

I'm a little stuck... Click here to teach me more about this clue!

'fan' is the definition.
(I've seen this before)

'abandoned farm vehicle' is the wordplay.
'abandoned' becomes 'ex' (I can't justify this - if you can you should believe this answer much more).
'farm vehicle' becomes 'tractor' (vehicle used on a farm).
'ex'+'tractor'='EXTRACTOR'

'found in' is the link.

Can you help me to learn more?

(Other definitions for extractor that I've seen before include "Remover" , "Kind of fan that sucks out stale air" , "Variety of fan" , "dentist" , "Device for removing air from a space" .)
