Plow body. Patented in the German Empire on April 28, 1910.

The purpose of the present invention is to avoid clogging of the plow by cut off a part of the earth beams to be turned and that on the unploughed field lying manure is covered with it. The long ones push themselves through this covering Straws of fertilizer not so easily under the leg. At the same time there is a shallower plowing under of the fertilizer achieved.

ίο The subject of the invention is in the drawing represented by two embodiments, namely shows

Fig. Ι a top view of the plow body, Fig. 2 is a side view from the land side.

The effect is based on the guide surface, which, in an opposite direction to the mouldboard Standing angle to the direction of travel, above the upper edge of the mouldboard, useful from the vertical cutting edge

so the plow deviates on the furrow side and extends to the land side.

Through this arrangement, coherent masses of earth, which with an ordinary plow usually get stuck in front of the leg, are placed on the land side on the still unploughed field. By covering the long straw manure, it is avoided that the manure becomes tangled, which easily pushes up on the leg with an ordinary plow. This guide surface α can now be extended laterally as desired (Fig. 1 and 2), so that this front part protrudes over the guide surface of the mouldboard, for the purpose of crumbling, inhibiting and distributing effect on the rising earth beam. The deeper this front part engages in the rising earth beam, the more soil is fed to the rear part of this guide surface and deposited on the land side, while at the same time more loose earth crumb is placed on the fertilizer through the outer front end of this arrangement just to be turned earth beam is located.

Fig. 2 shows a rotating disc which is suitable for humus or very tough Soil to carry out this aforementioned effect on the rising earth beam; the disc expediently only enters on one side Effect, in that its rear part is covered by the rest of the guide surface, and is Always rotated in the direction of the arrow due to the one-sided impact of the rising earth beam.

In order to make the plow as stable as possible, the leg b is expediently attached behind this rearrangement on the land side (Fig. 1) and can be connected to it above the guide surface extending forward.

Since the fertilizer is now covered with earth on the land side as well as in front of the plow, this arrangement also enables the field to be plowed deeply To store fertilizer much less deeply. At the same time there is no need for tractive effort the use of the skimmer or a special fertilizer skimmer.
