Drive farm animal (3)
I believe the answer is:
ram
I believe this is a double definition.
'drive' is the first definition.
('ram' can be a synonym of 'drive')
'farm animal' is the second definition.
(I've seen this before)
(Other definitions for ram that I've seen before include "man with many partners?" , "force" , "Aries is the Sign of the ..." , "Pound" , "Male sheep - bash into it" .)
