Description

Soil layers,

To achieve · the highest level of soil cooking as well as the fastest and most perfect Use of the manure to be plowed under, it is necessary that the bacteria-rich The top of the soil from the bacteria-poor subsoil, which is, as it were, dead, not covered when plowing and that the manure is plowed in as shallowly as possible, namely, the flatter, the heavier the ground

to is. This effect is achieved by a plow, which the soil in two superimposed Edited layers. The old plows of this kind suffer from the fact that the front, the coulter turning the upper crust is often not adjustable in depth; is continuous However, the mouldboard is not shaped so that there is even the lightest soil in a flat layer and l> completely turns the slow gait of the draft animals, and yet it is completely flat

ao plowed under stable or green manure for Achieving rapid decomposition also completely covered.

The subject of the above invention is a plow with two plow bodies for turning two layers of soil on top of each other separately. From these plow bodies the front one, which has to turn the upper crumb, and the turned upper crumb the turned lower crumb has to lay on a mouldboard, the edge of which facing the open furrow is almost right-angled is bent upwards and thus almost represents a horizontal wing. Through this is achieved that the bottom of the upper crumb, even if it is a dry, sandy Soil acts, even with the slowest gait of the draft animals, does not fall down from the mouldboard into the open furrow where it buries would. This wing of the mouldboard on the front plow body runs forward and pointed at the back, so that straw manure can be unimpeded over the edge of this Surface slides away. The rear part of the mouldboard is curved more like a screw, in order to cover the manure well even if the removed layer of the top crumb is only very weak. The horizontal wing of the mouldboard ends at the back where the screw-like Curvature of the mouldboard begins.

From the drawing, such a plow is in

Ploughshare can be seen in Figs. 3 and 4. Fig. 2 shows how the plow works.

Claims (2)

P ATENT claims: ι. Plow with two plow bodies for separate turning of two superimposed Soil layers, characterized in that on the mouldboard of the front plow body (α), which only the weak Remove the top crumb along with the fertilizer and move it by one furrow width should, at its lower edge facing the hollow furrow, a horizontal support surface is attached to prevent sliding to prevent the crumb. 2. Plow according to claim 1, characterized in that the horizontal wing ends where the stronger helical curvature of the mouldboard begins.
