Abstract
In the field of agricultural tillage, there is a need for accurate, automated control of the widths of tilling implements, such as ploughs. The invention concerns methods of controlling a plough operatively combined with a vehicle such as a tractor, the methods including logging a series of values of the strength of soil encountered during a pass along a field; selecting the most frequently occurring soil strength value; and, for a subsequent pass of the tractor/plough combination along the field in the same direction, setting the width of the plough in dependence on the most frequently logged soil strength value. A microprocessor is provided to carry out the methods of the invention.
