When ploughing a field with irregular (other than rectangular) shape with a trailed and semi-mounted reversible ploughs, unsymmetrical turns are produced – pear-shaped and eight-shaped. Correlations have been produced for determining the width of strip for turning when these turns are carried out. The way of cultivation of the field in which the width of strip for turning is minimum with different angle between the direction of movement of the unit and the border of the field is specified.
