The invention relates to a reversible plow suitable for border plowing, in which the plow frame is opposite the turning shaft is laterally displaceable and in the case of the turning shaft or the plow frame at least a side arm with a fastening device for the plow frame is provided.

In a known single furrow plow of this type, the entire plow frame is around a to Turning shaft pivoted parallel shaft. If the center of gravity of the plow frame is strongly eccentric, a great deal of force must be used to turn the plow into the border plowing position. As with two-furrowed Plowing the center of gravity would have to be relatively far outside the axis of rotation would be at the known construction requires a counterweight. This would make the plow a great deal of weight and would have to be built correspondingly strong and therefore expensive.

Also known is a plow which can be moved laterally at the same time by a single operation and is pivoted. This coupled movement creates a rotation around an ideal Pivot point achieved. The movement mechanism is relatively complex and is used in primarily for the appropriate relocation of the train point.

Furthermore, a border bed plow is known which, however, is not designed as a reversible plow. Moving to the side this border bed plow is achieved in that an articulated on the three-point linkage, The flap lying transversely to the direction of travel is rotated by 180 °, whereby the plow frame, the one on the other The end of this flap is hinged, is moved away from the center of the tractor to the outside. Solving the Plowing from the tractor is not necessary for this process.

The invention is intended to create a reversible plow in which the border plowing device is as possible is easily built and inexpensive to manufacture. The turning shaft should also largely be in the border plowing position be relieved of bending moments. The border plowing device is also intended for the use of the usual be suitable for double-furrow plows.

The plow according to the invention of the aforementioned type is characterized in that the fastening device can be rotated about a vertical axis joint forming, for example, a fork with bolts, is easily detachable and in that the plow frame with the fastening device in different seitlichöi _c ö distances from the longitudinal axis of the turnover shaft ;. can be coupled to this, wherein after the uncoupling; 'i

If this plow is to be used to move from the normal plowing position to the border plowing position, the plow must first be uncoupled from the tractor and set down on the ground. According to demrse.it; · borrowed displacement of the tractor compared to dPfi
