Adjusting the ridge cutting discs

The ridge cutting discs can be adjusted individually in the horizontal distance and in the horizontal and vertical tilt angle relative to the ridged row as well as in pairs in the height from the ridged rows. The different settings must be coordinated with each other.

For the adjustment, the following applies:

To ensure that the ridge flanks are shaved off with a uniform thickness during hoeing operation, the vertical tilt of the ridge cutting discs relative to the ridge must be adjusted such that the ridge flanks and the ridge cutting discs run parallel to one another.

The horizontal distance from a ridge cutting disc to the ridge must be adjusted such that the thickness S of the layer shaved off of the ridge flank during hoeing operation is 1 bis 2cm.

When the horizontal distance is greater and also the horizontal tilt is steeper relative to the ridged row, a ridge cutting disc disc cuts more soil from the ridge flank. When the horizontal distance is smaller and also the horizontal tilt is flatter relative to the ridged row, a ridge cutting disc disc cuts less soil from the ridge flank.

The height of the ridge cutting discs must be adjusted via the hoeing depth adjustment of the parallelogram so that the ridge flanks are not only partially shaved off during hoeing operation, but rather the full area B between the sole and the crown of the ridge is shaved off.

  1. To adjust the vertical tilt of a ridge cutting disc relative to the ridge:

    Follow steps 2 to 7.
  2. Lower the implement on the field with the three-point power lift.
  1. Loosen the nut 4 on the bolt 1.
  2. Unscrew the nut and pull the ridge cutting disc 5 to the rear until the cylinder dowel pins 3 no longer engage in the locking plate 2.
  1. Turn the ridge cutting disc 1 to the left or right around the longitudinal axis of the bolt 2 until the ridge cutting disc has the right vertical tilt.
  2. Push the ridge cutting disc to the front towards the locking plate 5 so that the cylinder dowel pins 3 slide into the locking holes.
  3. Tighten the nut 4 on the bolt.
  4. Adjust the vertical tilt for all of the ridge cutting discs in the same way.

  5. To adjust the horizontal distance of a ridge cutting disc:

    Follow steps 10 to 17.
  6. Lower the implement on the field with the three-point power lift.
  1. Loosen the nut 1 of the bolt 3 on the Vibro spring holder 5 so that the Vibro spring 4 can be moved together with the holder and ridge cutting disc 6 on the tool carrier 2.
  2. Move the ridge cutting disc inwards or outwards on the tool carrier until the ridge cutting disc is in the right position.
  3. Tighten the nut of the bolt on the Vibro spring holder.

  4. If the sliding path is not sufficient for the required position of the ridge cutting disc:

    Follow steps 15 to 17.
  1. Loosen the bolts 2 on the tool carrier 3.
  2. Move the ridge cutting disc 4 with the tool carrier outwards in the coulter bracket 1 until the ridge cutting disc is in the right position.
  3. Tighten the bolts on the tool carrier.
  4. Adjust the horizontal distance for all of the ridge cutting discs in the same way.

  5. To adjust the horizontal tilt of a ridge cutting disc:

    Follow steps 20 to 25.
  6. Lower the implement on the field with the three-point power lift.
  1. Loosen the nut 2 on the bolt 3.
  2. Unscrew the nut and lower the ridge cutting disc 1 until the cylinder dowel pins 4 no longer engage in the locking plate 5.
  1. Turn the ridge cutting disc 1 with the locking plate 3 to the left or right around the longitudinal axis of the bolt 5 until the ridge cutting disc has the right horizontal tilt.
  2. Press the ridge cutting disc up with the locking plate so that the cylinder dowel pins 6 slide into the locking holes 2.
  3. Tighten the nut 4 on the bolt.
  4. Adjust the horizontal tilt for all of the ridge cutting discs in the same way.

  1. To adjust the height of the ridge cutting discs on a parallelogram:

    Follow steps 28 to 30.
  2. Lower the implement on the field with the three-point power lift.
  3. Follow steps 2 to 6 in section Adjusting the hoeing depth on the KPP, Adjusting the hoeing depth on the KPP, until the ridge cutting discs are moved to the right height.
  4. Use the hoeing tools to compensate for the increased or reduced hoeing depth resulting from steps 2 to 5 of section Adjusting the hoeing depth on the EKP, Adjusting the hoeing depth on the EKP.
  5. Adjust the height of the ridge cutting discs on all of the parallelograms in the same way.
