Between the rows in a vineyard or hopfield, the soil is ploughed towards the centre one year, and towards the rows the next and deeper at the centre than

(U.S. Patent 1,327,413.) TANDEM HITCH. The side connecting scraps of the rear gang on this harrow keen the rear discs in proper alignment to strike the hills left
