Mover of livestock took the wheel, heading for ranch (6)
I believe the answer is:
drover
'mover' is the definition.
The answer and definition can be both people as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for drover that I've seen before include "One driving cattle" , "Man who herds cattle" , "Herdsman" , "Person guiding animals to market" , "Herder of cattle" .)
