Grass in furrow around front of field (4)
I believe the answer is:
turf
'grass' is the definition.
(I've seen this before)
'furrow around front of field' is the wordplay.
'furrow' becomes 'rut' ('rut' can be a synonym of 'furrow').
'around' shows that the letters should be reversed in order.
'front of' says to take the initial letters.
The initial letter of 'field' is 'f'.
'rut' backwards is 'tur'.
'tur'+'f'='TURF'
'in' acts as a link.
(Other definitions for turf that I've seen before include "Grass; (one's) territory" , "Divot" , "soil" , "Laid grass" , "Grass covering" .)
