The implement shown in the figure, raising the soil but slightly, may be worked with much less power, and produces equally good results. It may be run to a good depth in most soils by a single yoke of oxen. The motion of any part of the soil which is effected by this sub-soil plow is very slight, but it is exerted throughout the whole mass of the soil above the 9*.
