This is atheoretical study, design and invention, for it is considered like the ones available now. Precisely, it is aborne type which can be carried on a vehicle. The optimal design has been reached through making someprimary designs for the research on well excavated land by using spiral digging blades which unearths theearth on both sides. These blades are fixed on a subjacent system raised by a hydraulic tool when thedigging process finishes. This hydraulic tool enables to obtain a digging successive course by controllingthe process of lowering the lower system gradually to perform the digging processby a control system connected to the hydraulic tool.Throughout observation of the previous researches related to plowing [2, 3], it has been found that loadsare put on the most digging blades of the ploughs to increase the digging efficiency and to reach deeperpoints. This has been taken into account in our presented research by designing springs between the lowersystem mentioned above and the upper fixed system.From this we get a downward force which will be observed by detailed drawings. Besides, hinderingdigging blades by solid materials in the earth has been given attention for they penetrate the earth to a depthof (30 cm) by our designing the springs to raise the lower system when hindered and later to reach a systemdesign as a whole
