Farm vehicle reportedly followed over top of ridge (7)
I believe the answer is:
tractor
'farm vehicle' is the definition.
(I've seen this before)
'reportedly followed over top of ridge' is the wordplay.
'reportedly' indicates a 'sounds like' (homophone) clue.
'followed' becomes 'tracked' (to track is to follow or tail).
'over top of ridge' becomes 'or' (I can't justify this - if you can you should believe this answer much more).
'tracked' sounds like 'tract'.
'tract'+'or'='TRACTOR'
Can you help me to learn more?
(Other definitions for tractor that I've seen before include "Vehicle for pulling farm machinery" , "Farm machine used for pulling" , "Farming vehicle" , "Type of truck with a a cab but no body" , "I can draw" .)
