The farmer's means of guidance? (6)
I believe the answer is:
tiller
'the farmer's' is the definition.
(I've seen this in another clue)
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for tiller that I've seen before include "Bar used to turn rudder in small boat" , "steering contraption" , "Boat's steering bar" , "used to steer" , "Lever to move a boat's rudder" .)
