Transport turned to right that ploughs (7)
I believe the answer is:
tractor
'transport turned to right that ploughs' is the definition.
'tractor' can be an answer for 'transport' (tractor is a kind of transport). I am unsure of the remainder of the definition.
'transport turned to right' is the wordplay.
'transport' becomes 'cart' (carting is a kind of transporting).
'turned' says the letters should be written in reverse.
'right' becomes 'r' (common abbreviation).
'cart' reversed gives 'trac'.
'trac'+'to'+'r'='TRACTOR'
Can you help me to learn more?
(Other definitions for tractor that I've seen before include "Tower" , "I can draw" , "Vehicle for pulling others" , "Farm machine used for pulling" , "Powerful farm vehicle for heavy work" .)
