It can pull out old agricultural machinery (9)

Ross

I believe the answer is:

extractor

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

'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" .)
