Since the extent oi revolution oi the moldboard is through but substantiaily 180, it will be understood and as clearly represented in Figure 4, the longitudinal edges 42 and 43 oi the moldboard are in thereversed positions oi the moldboard also reversed as to top and bottom positioning. For this reason and in order that the moldboard will be equally eiiective in, both positions thereoi. I prefer to provide each oi the edges 42 and 43 with sharpened ground as blades 44 which as m the present case, may be removabiy secured to the moldboard by means oi bolts 46.
