The plows can work easily on rocky, stony and rooted surfaces. By the help of the rescues mechanisms placed on the back of each moldboard, it escapes for the plough not to be damaged. So breaking of wedge, detaching of nut, shrinking of chassis and degenerating of the plough are prevent.Each moldboard distance between following one another ones are elongated lineic, thus the weight made on tractor by the plough which is caused by the swelling of soil is prevented. Moldboard ploughs are the same in terms of construction and same parts are used in all of them. This is done to make the demand of spare parts easier.
