Such a will scour. A plow, for example, is given as close surface is capable of being finished by the abradto a proper shape as can be designed to meet a ing, polishing action of the earth moving across known soil condition and the curved turning surit, the dull surface being, in effect, burnished face is then ground and highly polished by a relto a smooth, good scouring condition. atively costly process to obtain a smooth surface. The dull smooth finish may be produced on Even so, the plows do not always scour satisfacthe surface quickly and effectively by forcing torily. It is believed that this failure of the tools small particles of an abrasive agent against the is due in part at least to the small lines and other surface. A wet blast method of surface treatirregularities produced in. the surface by the ment has been found to be quite effective in grinding wheel. producing a surface which is smooth, in which An object of the invention is to provide a plow 2 the minute projections from the surface are quite or like earth working implement which has a uniform and in which siu'face scratches or wheel smooth earth working surface of proper form marks are substantially absent.

The abrading ments as plows, listers, middlebusters ,andthe. like in which the earth working surfaces must scour. This term, of course, refers tothe 'movement of the earth across a surface freely, cleanly and without tending to adhere thereto.
