The Finish. The finish should be inch perfect. With a 2 furrow plough, the ploughman often calculate and adjust their ploughing to leave 3 unploughed furrow widths. In his
penultimate run the ploughman often sets the second of the 2 mouldboards on the plough to about one third to one half the depth so that on his final run he ploughs the one remaining furrow and re-ploughs deeper the shallow furrow, ideally to leave a narrow
trench, neatly cut and cleaned out with the finished work as level as possible. The work is judged again.
