Farm vehicle turned up, worked into drawing (8)
I believe the answer is:
traction
'drawing' is the definition.
(process of drawing or dragging)
'farm vehicle turned up worked into' is the wordplay.
'farm vehicle' becomes 'cart' (I've seen this before).
'turned up' is a reversal indicator.
'worked' is an anagram indicator.
'cart' backwards is 'trac'.
'into' is an anagram of 'tion'.
'trac'+'tion'='TRACTION'
(Other definitions for traction that I've seen before include "Action of drawing or pulling something" , "Which leaves on the line will affect" , "Gripping power to permit movement" , "Grip between something and the surface on which it moves" , "Pulling - into cart (anag)" .)
